cluster/afr: Do not attempt entry self-heal if the last lookup on entry failed on src

        Backport of: http://review.gluster.org/11119

Test bug-948686.t was causing shd to dump core due to gfid being NULL.
This was due to the volume being stopped while index heal's in progress,
causing afr_selfheal_unlocked_lookup_on() to fail sometimes on the src brick
with ENOTCONN. And when afr_selfheal_newentry_mark() copies the gfid off the
src iatt, it essentially copies null gfid. This was causing the assertion
as part of xattrop in protocol/client to fail.
