cli,nas: use '%u' for printing cell IDs
cli,nas: use '%u' for printing cell IDs

This patch fixes the following type mismatches in the format string for
printing cell IDs:

qmicli-nas.c:1271:71: error: format specifies type 'unsigned short' but the argument has type 'guint32' (aka 'unsigned int') [-Werror,-Wformat]
                    g_print ("\t\tCell ID: '%" G_GUINT16_FORMAT"'\n", cid);
                                            ~~~                       ^~~
