KVM: selftests: Use vcpu_get_cpuid_entry() in PV features test (sort of)

Browse source

Add a new helper, vcpu_clear_cpuid_entry(), to do a RMW operation on the
vCPU's CPUID model to clear a given CPUID entry, and use it to clear
KVM's paravirt feature instead of operating on kvm_get_supported_cpuid()'s
static "cpuid" variable.  This also eliminates a user of
the soon-be-defunct set_cpuid() helper.
