Subject: [PATCH v2 6/9] KVM: x86: Copy kvm_x86_ops by value to eliminate layer of indirection

Replace the kvm_x86_ops pointer in common x86 with an instance of the
struct to save one memory instance when invoking function.  Copy the
struct by value to set the ops during kvm_init().

Arbitrarily use kvm_x86_ops.hardware_enable to track whether or not the
ops have been initialized, i.e. a vendor KVM module has been loaded.

Suggested-by: Paolo Bonzini <pbonzini@...hat.com>
