The Flexible File layout LayoutReturn operation has argument fields where
an I/O error encountered when attempting I/O on a DS can be reported back
to the MDS.
This patch adds code to the client to do this for the Flexible File layout
mirrored case.
This patch should only affect mounts using the "pnfs" option against servers
that support the Flexible File layout.

When running mckey, errors may happen in the init/connect stage.
When leaving multicast groups, we override this value.
Fix that by saving the return value from rdma_leave_multicast to different
parameter, and only in case of failure in rdma_leave_multicast override it.

Normally the serial console is not enabled until /boot.config is read and
we know how the serial console should be configured. Initialize the
consoles early in 'dual' mode (serial & keyboard) with a default serial
rate of 115200. Then serial is re-initialized once the disk is decrypted
and the /boot.config file can be read.
This allows the GELIBoot passphrase to be provided via the serial console.

128MiB still works for Legacy booting, however. Go ahead and do 256MiB
for all amd64 boxes, since the number of such boxes < 256MiB is
vanishingly small.
Normally "soft,retrans=2" cannot be safely used on NFSv4 mounts, since
the RPC can fail and leave the open/lock state in an undefined state.
Doing I/O on a pNFS DS is an exception to this, since no open/lock state
is maintained on the DS server.
It is useful to do "soft,retrans=2" connections to a DS when it is mirrored,
so that the client can detect failure of the DS. As such, mounts from the MDS
to the DSs should use these mount options when mirroring is enabled.
However, the NFSv4.1 client still leaves the session in an undefined state
when this happens.
This patch fixes the problem by setting the session defunct, so it will
no longer be used.
The patch also sets "retries=2" on the connections done by the client to
a DS, which is the internal equivalent of "soft,retrans=2".
The client does not know if the server implements mirroring at connection
time, but always doing this should be safe, since it will fall back on doing
I/O via the MDS as a proxy when there is a failure doing an I/O RPC to the DS.
This patch should not affect non-pNFS client mounts.

The GELI boot code rounds reads up to 4k, since the encrypted sectors are
4k, and must be decrypted as a unit. With oddball sized disks (almost
always virtual), this can lead to reading past the end of the disk.

For most regulators, the regulator_stop() method can be transformed to
regulator disable. But, in some cases, we needs to maintain shared data
across multiple regulators (e.g. single GPIO pin which works as enable
for multiple regulates). In this case, the implementation of regulator
should perform his own enable counting therefore it is necessary to
distinguish between the regulator enable/disable method (which
increments/decrements enable counter for shared resource) and regulator
stop method (which don't affect it).
So:
- add regnode_stop() method to regulator framework and default it to
regnode_enable(..., false, ...)
- implement it in regulator_fixed with proper enable counting.
While I'm in, also fix handling of always_on property. If any of regulators
sharing same GPIO pin have it enabled, then none of them can disable regulator.

`rdev` and `disk` serve the same purpose, read the partition table without
the `d_offset` or `d_slice` set, so the read is relative to the start of
the disk. Reuse the already initialized `disk` instead of making another
copy later.
