[SCSI] enable destruction of blocked devices which fail LUN scanning
If something goes wrong during LUN scanning, e.g. a transport layer failure occurs, then __scsi_remove_device() can get invoked by the LUN scanning code for a SCSI device in state SDEV_CREATED_BLOCK and before the SCSI device has been added to sysfs (is_visible == 0). Make sure that even in this case the transition into state SDEV_DEL occurs. This avoids that __scsi_remove_device() can get invoked a second time by scsi_forget_host() if this last function is invoked from another thread than the thread that performs LUN scanning.
