Mike Snitzer ffc41cf8db nbd: prevent sock_xmit from attempting to use a NULL socket 
NBD does not protect the nbd_device's socket from becoming NULL during
receives.

This closes a race with the NBD_CLEAR_SOCK ioctl (nbd-client -d) setting
the nbd_device's socket to NULL right before NBD calls sock_xmit.
