md/raid1/raid10: add a cond_resched

commit 1d9d52416c0445019ccc1f0fddb9a227456eb61b upstream.

During 'check' of a raid1 or raid10 it is possible for the management
thread to spend a lot of time running 'memcmp' on blocks from
different devices, so make sure the thread has a chance to schedule.
raid5d already has a cond_resched (in process_stripe).
