Its possible for __break_lease to find the layout's lease before we've
added the layout to the owner's ls_layouts list. In that case, setting
ls_recalled = true without actually recalling the layout will cause the
server to never send a recall callback.
Move the check for ls_layouts before setting ls_recalled.
