[PATCH] md: Make sure an interrupted resync doesn't seem to have completed.

From: NeilBrown <neilb@cse.unsw.edu.au>

If the raid1 or raid5 thread gets to run md_check_recovery after the recovery
thread has been interupted, but before do_md_stop completes, a spare drive
can be incorporated into an array befure it is up-to-date.

This patch corrects the relevant test.
