This patch closes a window where if a device had a cancel all
outstanding as a result of a check condition and the adapter
was reset for some reason, a request sense would still be issued,
which would end up timing out and issuing an additional adapter
reset. It could also result in a leak of command blocks, depending
on when it timed out.
