Dan Williams 9851882600 md/raid5: STRIPE_ACTIVE has lock semantics, add barriers ...

commit 257a4b42af7586fab4eaec7f04e6896b86551843 upstream.

All updates that occur under STRIPE_ACTIVE should be globally visible
when STRIPE_ACTIVE clears.  test_and_set_bit() implies a barrier, but
clear_bit() does not.

This is suitable for 3.1-stable.
