[media] usb/cpia2_core: clean up a min_t() cast
It makes sense to make the min_t() cast unsigned here since we don't
really want negative sizes. Making it signed causes a static checker
warning in Smatch. Smatch knows "fw->size - i" is positive but it
doesn't know that fw->size is less than INT_MAX so in theory casting it
to int might lead to a negative.
