[ Upstream commit cf25ae78fc ]
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 824e47dadd ("RAID1: avoid unnecessary spin
locks in I/O barrier code") which has already added the
wake_up for raid1.
