KVM: x86: Insert "AMD" in KVM_X86_FEATURE_PSFD

Browse Source 
Intel and AMD have separate CPUID bits for each SPEC_CTRL bit. In the
case of every bit other than PFSD, the Intel CPUID bit has no vendor
name qualifier, but the AMD CPUID bit does. For consistency, rename
KVM_X86_FEATURE_PSFD to KVM_X86_FEATURE_AMD_PSFD.

No functional change intended.
