gfs2: Simplify the buf_limit and databuf_limit definitions
The BUF_OFFSET and DATABUF_OFFSET definitions are only used in buf_limit and databuf_limit, respectively, and the rounding done in those definitions is immediately wiped out by dividing by the element size. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
