Because gfs2_decode_fh only accepts file handles with GFS2_LARGE_FH_SIZE
or GFS2_LARGE_FH_SIZE you don't accept filehandles sent out by and older
gfs version anymore.  Stale filehandles because of a new kernel version
are a big no-no, so please add back code to handle the old filehandles
on the decode side.
