btrfs: document existence of extent_io ops callbacks Some of the callbacks defined in btree_extent_io_ops and btrfs_extent_io_ops do always exist so we don't need to check the existence before each call. This patch just reorders the definition and documents which are mandatory/optional. Signed-off-by: David Sterba <dsterba@suse.com>
