[CPUFREQ] arch/x86/kernel/cpu/cpufreq: Fix unsigned return type
In each case, the function has an unsigned return type, but returns a
negative constant to indicate an error condition. Each function is only
called once. For nforce2_detect_chipset, the result is only compared to 0,
and for longrun_determine_freqs, the result is stored in a variable of type
(signed) int. Thus, for both functions, unsigned can be dropped from the
return type.
A sematic match that finds this problem is as follows:

// <smpl>

identifier f;
constant C;

unsigned f(...)
{ <+...
* return -C;
...+> }
// </smpl>
