[PATCH 2/5] btrfs: remove the unused bio_flags argument to btrfs_submit_metadata_bio

[Christoph Hellwig <hch@lst.de>]

This argument is unused since commit 953651eb308f ("btrfs: factor out
helper adding a page to bio") and commit 1b36294a6cd5 ("btrfs: call
submit_bio_hook directly for metadata pages") reworked the way metadata
bio submission is handled.
