md/raid10: wait up frozen array in handle_write_completed
Since nr_queued is changed, we need to call wake_up here if the array is already frozen and waiting for condition "nr_pending == nr_queued + extra" to be true. And commit 824e47daddbf ("RAID1: avoid unnecessary spin locks in I/O barrier code") which has already added the wake_up for raid1.
