[PATCH v2] staging: most: video: use min_t() for comparison and assignment

[Deepak R Varma <drv@mailo.com>]

Simplify code by using min_t helper macro for logical evaluation
and value assignment. Use the _t variant of min macro since the
variable types are not same.
This issue is identified by coccicheck using the minmax.cocci file.
