Bob Peterson cb9e778a29 gfs2: fix glock reference problem in gfs2_trans_remove_revoke ... [ Upstream commit fe5e7ba11fcf1d75af8173836309e8562aefedef ] Commit 9287c6452d fixed a situation in which gfs2 could use a glock after it had been freed. To do that, it temporarily added a new glock reference by calling gfs2_glock_hold in function gfs2_add_revoke. However, if the bd element was removed by gfs2_trans_remove_revoke, it failed to drop the additional reference. This patch adds logic to gfs2_trans_remove_revoke to properly drop the additional glock reference.
