Revert "gfs2: Fix use of bio_chain"

Browse Source 
This reverts commit 8a157e0a0a.

That commit incorrectly assumed that the bio_chain() arguments were
swapped in gfs2.  However, gfs2 intentionally constructs bio chains so
that the first bio's bi_end_io callback is invoked when all bios in the
chain have completed, unlike bio chains where the last bio's callback is
invoked.
