...
Suspend:
- Prevent the backend from being touched on TX path.
- Clear the RNDIS RX filter, and wait for RX to drain.
- Make sure that NVS see the chimney sending buffer and RXBUF
disconnection, before unlink these buffers from the channel.
Resume:
- Reconfigure the RNDIS filter.
- Allow TX path to work on the backend.
- Kick start the TX eof task, in case the OACTIVE is set.
This fixes various panics, when the interface has traffic and MTU
is being changed.

...
- By default, adjust time upon SYNC request. It can be disabled
through hw.hvtimesync.ignore_sync_req. SYNC request will be
sent by hypervisor the host is resumed, rebooted, etc.
- By default, adjust time upon SAMPLE request, if there is 100ms
difference between VM time and hypervisor time. This can be
disabled through hw.hvtimesync.sample_drift.
And nuke the unnecessary task, since channel callback is running
in a Hyper-V taskqueue nowadays.

SRB status is set to 0x20 by the hypervisor, if the specified LUN is
unaccessible, and even worse the INQUIRY response will not be set by
the hypervisor at all under this situation. Additionally, SRB status
is 0x20 too, for TUR on an unaccessible LUN.
Deliver CAM_SEL_TIMEOUT to CAM upon SRB status errors as suggested by
Scott Long, other values seems improper.

hyperv/vmbus: Fix the racy channel close.
...
It is not safe to iterate the sub-channel list w/o lock on the
close path, while it's even more difficult to hold the lock
and iterate the sub-channel list. We leverage the
vmbua_{get,rel}_subchan() functions to solve this dilemma.
