The call to btrfs_mark_buffer_dirty() at btrfs_uuid_tree_add() is not
necessary as we have a path setup for writing with btrfs_search_slot()
having a 'cow' argument set to 1 (through btrfs_insert_empty_item()).

This just makes the code more verbose, confusing and add a little extra
overhead and well as increase the module's text size, so remove it.
