[SCSI] bsg: takes a ref to struct device in fops->open
bsg_register_queue() takes a ref to struct device that a caller
passes. For example, bsg takes a ref to the sdev_gendev for scsi
devices. However, bsg doesn't inrease the refcount in fops->open. So
while an application opens a bsg device, the scsi device that the bsg
device holds can go away (bsg also takes a ref to a queue, but it
doesn't prevent the device from going away).
With this patch, bsg increases the refcount of struct device in
fops->open and decreases it in fops->release.
