fwts: memory leak when reading MSRs when checking if check if CPU has C1E bit

[Colin Ian King]

Resource leak on failed MSR read. Minor issue, should be fixed.

226 if (fwts_cpu_readmsr(0, MSR_AMD64_OSVW_STATUS, &val) != FWTS_OK)
   CID 1351543 (#2 of 2): Resource leak (RESOURCE_LEAK)11. leaked_storage: Variable cpu going out of scope leaks the storage it points to.
227 return FWTS_BOOL_ERROR;
228 if (!(val & 2)) {
229 fwts_cpu_free_info(cpu);
230 return FWTS_FALSE;

I also noticed that we need to fix the case when family 0x0f models < rev F do not have C1E, the code was erroneously returning true instead of false.
