[SCSI] bsg: correct fault if queue object removed while dev_t open
This patch corrects an issue in bsg that results in a general protection
fault if an LLD is removed while an application is using an open file
handle to a bsg device, and the application issues an ioctl. The fault
occurs because the class_dev is NULL, having been cleared in
bsg_unregister_queue() when the driver was removed. With this
patch, a check is made for the class_dev, and the application
will receive ENXIO if the related object is gone.
