7dcc2507f6 bdev/lvol: asserting lvol ptr before dereference
Klocwork filtered it out that there is a dereference
of pointer 'lvol' before its NULL check.

dbdf54f1c9 bdev/lvol: unload empty lvs during fini_start
This patch makes use of async_fini_start flag to
make fini_start asynchronous.

During this time all lvol stores which have no open
lvols are unloaded. This is required, since lvs
holds claim on the underlying bdev.

Fixes #1630

d2dd47433b bdev/lvol: remove lvs with lvols during application shutdown
Once bdev finish starts, bdev unregister is called on all
unclaimed bdevs. This means that for lvs with at least one
lvol present, there will be a corresponding bdev unregister.

Yet the vbdev_lvol module does not attempt to unload the lvs,
once last lvol from that lvs is unregistered. Leaving
the base bdev for lvs claimed.

This patch fixes that by using fini_start callback from
bdev_module to mark when shutdown begins. After that
last lvol unregistered on lvs will unload it.

Expanded struct lvol_bdev to contain lvol_store_bdev.
Closing the lvol will free spdk_lvol, so lvol->lvol_store cannot
be accessed.

Changed ut_lvol_destroy UT to ut_bdev_finish. Previous UT didn't
really test vbdev_lvol_destroy, but 'hotremove' of the lvol bdev.
In effect there is no hotremove of the lvol bdevs (only lvs bdev).
spdk_bdev_unregister() can only be called from within vbdev_lvol,
or during bdev module finish.
This UT will now check the bdev module finish.

Note that at this point lvs with no lvols will not trigger
lvs unload. Next patches in series will introduce async fini_start,
to allow for the unload.

In the bdev_multi_allocation test, we can get 3x ~ 5x speed up when
creating multiple bdevs for various bdev nums.

4e4c293b9a lvol: do not use task->status
There is no point in setting this value on submission
and changing it on callback.
Since it is based on blob bserrno.

lvol_task is removed in next patch.

This change was motivated by lvol_op_comp() accessing
the task->status pointer on hot path for I/O.
There is no need to do so, so just pass status.
