[GFS2] Fix leak of gfs2_bufdata
This fixes a memory leak of struct gfs2_bufdata and also some problems in the ordered write handling code. It needs a bit more testing, but I believe that the reference counting of ordered write buffers should now be correct. This is aimed at fixing Red Hat bugzilla: #201028 and #201082 Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
