block/amend: Always call .bdrv_amend_clean()

.bdrv_amend_clean() says block drivers can use it to clean up what was
done in .bdrv_amend_pre_run().  Therefore, it should always be called
after .bdrv_amend_pre_run(), which means we need it to call it in the
JobDriver.free() callback, not in JobDriver.clean().
