target/i386: Assert !SVME for user-only
Most of the VMM instructions are already disabled for user-only,
by being usable only from ring 0.
The spec is intentionally loose for VMMCALL, allowing the VMM to
define syscalls for user-only. However, we're not emulating any
VMM, so VMMCALL can just raise #UD unconditionally.
