GFS2: Eliminate needless parameter from function gfs2_setbit
This patch eliminates parameter "buf1" from function gfs2_setbit. This is possible because it was always passed in as bi->bi_bh->b_data. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
