foreach_session() is used to e.g. close a bdev, where
for each session we close any io_channels and then,
on the final "finish" call, close the bdev descriptor.
The vhost init thread is the one that called
spdk_vhost_init() and also the same one that calls
all management APIs. One of those is for hotplugging
LUNs to vhost scsi targets, which practically results
in opening bdev descriptors.
By always scheduling that final foreach_session()
callback to the init thread, we end up with calling
spdk_bdev_close() always on the same thread which
called spdk_bdev_open(), which is actually a bdev
layer requirement.

We used to call potentially-asynchronous foreach_session()
in vdev initialization path and that was perfectly
fine because at that time there were no sessions created
and foreach_session() was always finishing synchronously.
We're about to refactor it to be always asynchronous, and
for this coalescing case it could complicate the init
error path. Once asynchronous thread msg is sent, we would
need to wait for it to complete and we just don't want to
do that. We want error handling to be simple.
Since we know there are no sessions at the time of vdev
creation, we just add a new function for setting coalescing
params just for vdev (and not for its sessions) and we
use that function in vdev init code.

By making dpdk device detach asynchronous we have
actually broken some cases where devices are re-attached
immediately after and fail since they were not detached
yet, so now we're making device detach synchronous again.
For that we'll simply wait inside spdk_pci_device_detach()
for the background dpdk thread to perform all necessary
actions before we return. We'll also print an error msg
if DPDK failed the detach (probably because of some
internal error).

We'll need to make detach synchronous again, and for that
we'll wait for the background dpdk thread to perform all

However, device detach could be triggered from the very
same dpdk background thread as well. Waiting there would
cause a deadlock, so now we'll schedule asynchronous
device detach to the dpdk thread only if we're not on
that thread already.
This patch itself serves also as an optimization.

To test the failing paths, two compile time defines were added to force a

Added ftl_dev_has_nv_cache to check if the FTL is configured to use
non-volatile cache or not. It makes these checks a bit more readable.

Wait until all user writes are completed before writing band's metadata.
Otherwise in case of power loss, user data might not get written while
the metadata does, which would result in data loss.

Use the data placed on the non-volatile cache to perform recovery in
case the device wasn't shut down cleanly. The write phase ranges are
read and their data is copied onto the OC device.
The code added in this patch will correctly copy the data from
overlapping ranges, however it won't do anything about these overlapping
areas, so subsequent power loss happening quickly after recovery might
result in data loss.

Scan the cache to find ranges of blocks written with the same phase.
This prepares the structures needed to perform data recovery from the
non-volatile cache.
