[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>
@exists@
identifier f;
constant C;
@@

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