This adds an extra argument to gfs2_trans_add_bh() to indicate whether the
bh being added to the transaction is metadata or data. Its currently unused
since all existing callers set it to 1 (metadata) but following patches will
make use of it.

We no longer allocate a dinode on the stack in init_dinode()
and we no longer use gfs2_dinode_out (eliminating one copy) and
gfs2_meta_header_in (eliminating another copy). The meta_header_in
fucntion is now no longer referenced from outside gfs2_ondisk.c, so
make it static.
