md: cancel check/repair requests when recovery is needed

If a 'repair' is requested when an array is in a position to 'recover' raid1
will perform the repair while md believes a recovery is happening.  Address
this at both ends, i.e. cancel check/repair requests upon detecting a
recover condition and do not call ->spare_active after completing a
check/repair.
