btrfs_writepage_endio_finish_ordered is a small wrapper around
btrfs_mark_ordered_io_finished that just changs the argument passing
slightly, and adds a tracepoint.
Move the tracpoint to btrfs_mark_ordered_io_finished, which means
it now also covers the error handling in btrfs_cleanup_ordered_extent
and switch all callers to just call btrfs_mark_ordered_io_finished
directly.
