[PATCH v5 01/18] kvm: x86: Modify kvm_x86_ops.get_enable_apicv() to use struct kvm parameter

Generally, APICv for all vcpus in the VM are enable/disable in the same
manner. So, get_enable_apicv() should represent APICv status of the VM
instead of each VCPU.

Modify kvm_x86_ops.get_enable_apicv() to take struct kvm as parameter
instead of struct kvm_vcpu.
