Hou Wenlong d5f6f44e04 KVM: x86/emulator: Emulate RDPID only if it is enabled in guest ...

[ Upstream commit a836839cbf ]

When RDTSCP is supported but RDPID is not supported in host,
RDPID emulation is available. However, __kvm_get_msr() would
only fail when RDTSCP/RDPID both are disabled in guest, so
the emulator wouldn't inject a #UD when RDPID is disabled but
RDTSCP is enabled in guest.
