gfs2: a minor finish_xmote cleanup

Browse Source 
As a minor clean-up to commit 1fc05c8d84 ("gfs2: cancel timed-out
glock requests"), when a demote request is in progress in
finish_xmote(), there is no point in waking up the glock holder at the
head of the queue because the reply from dlm cannot be on behalf of that
glock holder.
