fs: remove _submit_bh()
_submit_bh() allowed submitting a buffer_head for I/O using custom
bio_flags. It used to be used by jbd to set BIO_SNAP_STABLE, introduced
by commit 713685111774 ("mm: make snapshotting pages for stable writes a
per-bio operation"). However, the code and flag has since been removed
and no _submit_bh() users remain.
These days, bio_flags are mostly used internally by the block layer to
track the state of bio's. As such, it doesn't really make sense for
filesystems to use them instead of op_flags when wanting special
behavior for block requests.
Therefore, remove _submit_bh() and trim the bio_flags argument from
submit_bh_wbc().
