cpu/x86/mtrr/mtrr.c:Avoid static scan false positive
Static scan does not know the contents of the fixed MTRR descriptor, so
it has no way to eval the result for variable num_ranges. If num_ranges
is less or equal to 0, the for loop will not be entered, and the values
of fixed_msrs will not be set. Asserting that num_ranges is greater than
0 ensures the loop enters at least once.
