xfs: cancel dfops on xfs_defer_finish() error
The current semantics of xfs_defer_finish() require the caller to call xfs_defer_cancel() on error. This is slightly inconsistent with transaction commit error handling where a failed commit cleans up the transaction before returning. More significantly, the only requirement for exposure of ->dop_pending outside of xfs_defer_finish() is so that xfs_defer_cancel() can drain it on error. Since the only recourse of xfs_defer_finish() errors is cancellation, mirror the transaction logic and cancel remaining dfops before returning from xfs_defer_finish() with an error. Beside simplifying xfs_defer_finish() semantics, this ensures that xfs_defer_finish() always returns with an empty ->dop_pending and thus facilitates removal of the list from xfs_defer_ops.
