st/mesa: fix reporting of float perf counters max value

Some Piglit tests (rightfully) fail because of min >= max when exposed
to perf counters that do not explicitly define their max value.

Failing tests:
spec/amd_performance_monitor/api/test_counter_info
spec/amd_performance_monitor/vc4/test_counter_info

u32/u64 changes are no-ops.

Fixes: 4cd1cfb9831d ("st/mesa: implement GL_AMD_performance_monitor")
