nbd: add locking to nbd_ioctl
The code was written to rely on big kernel lock to protect it from races.
It mostly works when interface is not abused.
So this uses tx_lock to protect data structures from concurrent use
between ioctl and worker threads.
Next step will be moving from ioctl to unlocked_ioctl.
