util: mark s as MAYBE_UNUSED in _mesa_half_to_unorm8
Only used, when asserts are enabled.
Fixes an unused-variable warning with gcc-8:
../../../src/util/half_float.c: In function '_mesa_half_to_unorm8':
../../../src/util/half_float.c:189:14: warning: unused variable 's' [-Wunused-variable]
const int s = (val >> 15) & 0x1;
