From: Omar Sandoval <osandov@xxxxxx>
get_block() already has access to this through bh_result->b_private, and
it gets passed to end_io() as private, so do the same for submit_io().
Along with the previous change, this will allow us to get rid Btrfs'
current->journal_info abuse in btrfs_direct_IO().
