Christoph Hellwig 409e0ff10e nbd: reset NBD to NULL when restarting in nbd_genl_connect 
When nbd_genl_connect restarts to wait for a disconnecting device, nbd
needs to be reset to NULL.  Do that by facoring out a helper to find
an unused device.

Fixes: 6177b56c96 ("nbd: refactor device search and allocation in nbd_genl_connect")
