md: update curr_resync_completed even when MD_RECOVERY_INTR is set

An error sync IO may be done and sub 'recovery_active' while its
error handling work is pending. This work sets 'recovery_disabled'
and MD_RECOVERY_INTR, then later removes the bad disk without Faulty
flag. If 'curr_resync_completed' is updated before the disk is removed,
it could lead to reading from sync-failed regions.

With the previous patch, error IO will set badblocks or mark rdev as
Faulty, sync-failed regions are no longer readable. After waiting for
'recovery_active' to reach 0 (in the previous line), all sync IO has
*completed*, regardless of whether MD_RECOVERY_INTR is set. Thus, the
MD_RECOVERY_INTR check can be removed.
