KVM: x86 emulator: fix repne/repnz decoding

The repnz/repne instructions must set rep_prefix to 1 like rep/repe/repz.

This patch correct the disk probe problem met with OpenBSD.

This issue appears with commit e70669abd4e60dfea3ac1639848e20e2b8dd1255
because before it, the decoding was done internally to kvm and after it
is done by x86_emulate.c (which doesn't do it correctly).
