This function is a simple wrapper over btrfs_get_extent that returns either: a) A real extent in the passed range or b) Adjusted extent based on whether delalloc bytes are found backing up a hole. To support these semantics it doesn't need the page/pg_offset/create arguments which are passed to btrfs_get_extent in case an extent is to be created. So simplify the function by removing the unused arguments. No functional changes.
