btrfs: remove the unused @locked_folio parameter from

btrfs_cleanup_ordered_extents()

The function btrfs_cleanup_ordered_extents() is only called in error
handling path, and the last caller with a @locked_folio parameter is
removed to fix a bug in the btrfs_run_delalloc_range() error handling.

There is no need to pass @locked_folio parameter anymore.
