Tom Lendacky e70316d17f x86/sev: Check for MWAITX and MONITORX opcodes in the #VC handler ...

The MWAITX and MONITORX instructions generate the same #VC error code as
the MWAIT and MONITOR instructions, respectively. Update the #VC handler
opcode checking to also support the MWAITX and MONITORX opcodes.

Fixes: e3ef461af3 ("x86/sev: Harden #VC instruction emulation somewhat")
