KVM: x86 emulator: fix group3 instruction decoding

Group 3 instruction with ModRM reg field as 001 is
defined as test instruction under AMD arch, and
emulate_grp3() is ready for emulate it, so fix the
decoding.

static inline int emulate_grp3(...)
{
	...
	switch (c->modrm_reg) {
	case 0 ... 1:   /* test */
		emulate_2op_SrcV("test", c->src, c->dst, ctxt->eflags);
	...
}
