net: qrtr: ns: Ignore ENODEV failures in ns

Ignore the ENODEV failures returned by kernel_sendmsg(). These errors
indicate that either the local port has been closed or the remote has
gone down. Neither of these scenarios are fatal and will eventually be
handled through packets that are later queued on the control port.
