GFS2: Don't try to end a non-existent transaction in unlink
Before this patch, if function gfs2_unlink failed to get a valid transaction (for example, not enough journal blocks) it would go to label out_end_trans which did gfs2_trans_end. But if the trans_begin failed, there's no transaction to end, and trying to do so results in: kernel BUG at fs/gfs2/trans.c:117! This patch changes the goto so that it does not try to end a non-existent transaction. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
