md: close a livelock window in handle_parity_checks5
If a failure is detected after a parity check operation has been initiated,
but before it completes handle_parity_checks5 will never quiesce operations on
the stripe.
Explicitly handle this case by "canceling" the parity check, i.e. clear the
STRIPE_OP_CHECK flags and queue the stripe on the handle list again to refresh
any non-uptodate blocks.
Kernel versions >= 2.6.23 are susceptible.
