Jim Harris 1f935c7a9b bdev: properly handle aborted resets
Previously, we naively assumed that a completed
reset was the reset in progress, and would
unilaterally set reset_in_progres to false.

So change reset_in_progress to a bdev_io pointer
instead.  If this is not NULL, a reset is not in
progress.  Then when a reset completes, we only
set the reset_in_progress pointer to NULL if we
are completing the reset that is in progress.

We also were not aborting queued resets when
destroying a channel so that is fixed here too.

The added unit test covers both fixes above - it will
submit two resets on a different channels, then destroy
the second channel.  This will abort the second reset
and check that the bdev still sees the first reset as in
progress.
