KVM: x86: Remove x86_emulate_ops::guest_has_long_mode

Browse Source 
Remove x86_emulate_ops::guest_has_long_mode along with its implementation,
emulator_guest_has_long_mode(). It has been unused since commit
1d0da94cda ("KVM: x86: do not go through ctxt->ops when emulating rsm").

No functional change intended.
