btrfs: pass an ordered_extent to btrfs_submit_compressed_write
btrfs_submit_compressed_write always operates on a single ordered_extent.
Make that explicit by using btrfs_alloc_ordered_extent in the callers
and passing the ordered_extent to btrfs_submit_compressed_write. This
will help with storing and ordered_extent pointer in the btrfs_bio in
subsequent patches.
