KVM: x86: Use "is Intel compatible" helper to emulate SYSCALL in !64-bit

Browse source

Use guest_cpuid_is_intel_compatible() to determine whether SYSCALL in
32-bit Protected Mode (including Compatibility Mode) should #UD or succeed.
The existing code already does the exact equivalent of
guest_cpuid_is_intel_compatible(), just in a rather roundabout way.

No functional change intended.
