Rakesh Pandit 75ba4ada82 ligtnvm: fix double blk_put_queue on same queue 
On an error path in NVM_DEV_CREATE ioctl blk_put_queue is being called
twice: one via blk_cleanup_queue and another via put_disk.  Straight fix
seems to remove queue pointer so that disk_release never ends up caling
blk_put_queue again.
