Even when urgent BKOPS fails, the consumer will get stuck in runtime
suspend status. Like commit
1a5665fc8d7a ("scsi: ufs: core: WLUN suspend
SSU/enter hibern8 fail recovery"), trigger the error handler and return
-EBUSY to break the suspend.
Fixes: b294ff3e3449 ("scsi: ufs: core: Enable power management for wlun")
