[PATCH] staging: most: video: Use min_t() macro for type safety

[Vojtěch Krátký]

Replace the open-coded ternary operator matching a minimum calculation
with the standard kernel min_t() macro. Because 'count' is a size_t
and 'rem' is a signed integer, comparing them directly introduces a
signed/unsigned comparison risk. Forcing both to size_t via min_t()
ensures safely typed comparison and fixes a build-time macro assertion.
