Ensure minimum value

(In reply to Noah Goldstein from comment #2)
> Sorry wasn't clear, does that fix the issue?

No. Now --list-tunables reports:

    glibc.cpu.x86_non_temporal_threshold: 0x0 (min: 0x4040, max:
0xffffffffffffffff)

The attached patch fixes the problem that the default value is never checked
against the limits.
