[PATCH 06/18] media: siano: Refactor struct sms_msg_data

[Ricardo Ribalda]

Replace a single element array with a single element field.

This fixes the following cocci warning:
drivers/media/common/siano/smscoreapi.h:619:5-13: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
