test_kmod: remove paranoid UINT_MAX check on uint range processing

test_kmod: remove paranoid UINT_MAX check on uint range processing

The UINT_MAX comparison is not needed because "max" is already an unsigned
int, and we expect developer C code max value input to have a sensible 0 -
UINT_MAX range.  Note that if it so happens to be UINT_MAX + 1 it would
lead to an issue, but we expect the developer to know this.
