md: raid10: wake up frozen array

When rescheduling a bio in raid10, we wake up
the md thread, but if the array is frozen, this
will have no effect.  This causes the array to
remain frozen for eternity.  We add a wake_up
to allow the array to de-freeze.  This code is
nearly identical to the raid1 code, which has
this fix already.
