md: do_release_stripe(): No need to call md_wakeup_thread() twice
67f455486d2ea20b2d94d6adf5b9b783d079e321 introduced a call to md_wakeup_thread() when adding to the delayed_list. However the md thread is woken up unconditionally just below. Remove the unnecessary wakeup call. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>
