null_blk: Cleanup error recovery in null_add_dev()
When creation of queues fails in init_driver_queues(), we free the
queues. But null_add_dev() doesn't test for this failure and continues
with the setup leading to strange consequences, likely oops. Fix the
problem by testing whether init_driver_queues() failed and do proper
error cleanup.
