KVM: x86: Drop explicit @func param from ->set_supported_cpuid()
Drop the explicit @func param from ->set_supported_cpuid() and instead
pull the CPUID function from the relevant entry. This sets the stage
for hardening guest CPUID updates in future patches, e.g. allows adding
run-time assertions that the CPUID feature being changed is actually
a bit in the referenced CPUID entry.
No functional change intended.
