GFS2: put glock reference in error patch of read_rindex_entry
This patch fixes the error path of function read_rindex_entry so that it correctly gives up its glock reference in cases where there is a race to re-read the rindex after gfs2_grow. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
