nfsd: fix race to check ls_layouts
[ Upstream commit fb610c4dbc996415d57d7090957ecddd4fd64fb6 ] 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.
