[PATCH 13/19] [media] uvc_video: Use kmalloc_array() in uvc_video_clock_init()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".

This issue was detected by using the Coccinelle software.
