KVM: VMX: Check CPU_BASED_{INTR,NMI}_WINDOW_EXITING in setup_vmcs_config()
CPU_BASED_{INTR,NMI}_WINDOW_EXITING controls are toggled dynamically by
vmx_enable_{irq,nmi}_window, handle_interrupt_window(), handle_nmi_window()
but setup_vmcs_config() doesn't check their existence. Add the check and
filter the controls out in vmx_exec_control().
Note: KVM explicitly supports CPUs without VIRTUAL_NMIS and all these CPUs
are supposedly lacking NMI_WINDOW_EXITING too. Adjust cpu_has_virtual_nmis()
accordingly.
No functional change intended.
