[PATCH] md: fix rdev->pending counts in raid1

Browse Source 
When we do a user-requested check/repair, we lose count of the outstanding
requests...

Also make sure that when anything is written to md/sync_action, the
RECOVERY_NEEDED flag is set and the thread is woken up so any changes take
effect.
