gfs2: Add missing else in trans_add_meta/data
This patch fixes a timing window that causes a segfault. The problem is that bd can remain NULL throughout the function and then reference that NULL pointer if the bh->b_private starts out NULL, then someone sets it to non-NULL inside the locking. In that case, bd still needs to be set. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
