DIAG_CMD_OP_SET_ALL_MSG_MASK broadcasts with a null ssid range, but `diag_cntl_send_msg_mask()` dereferences the range pointer and segfaults when enabling all F3 message masks. Fix the null (broadcast all) case, and send every real ssid range via the appropriate function. Signed-off-by: adisbladis <adisbladis@gmail.com>
