scsi_debug: deadlock between completions and surprise module removal
A deadlock has been reported when the completion
of SCSI commands (simulated by a timer) was surprised
by a module removal. This patch removes one half of
the offending locks around timer deletions. This fix
is applied both to stop_all_queued() which is were
the deadlock was discovered and stop_queued_cmnd()
which has very similar logic.
This patch should be applied both to the lk 3.17 tree
and Christoph's drivers-for-3.18 tree.
