[Qemu-ppc] [PULL 4/6] ppc: Fix fault PC reporting for lve*/stve* VMX instructions

[David Gibson]

From: Benjamin Herrenschmidt <address@hidden>

We forgot to do gen_update_nip() for these like we do with other
helpers. Fix this, but in a more efficient way by passing the RA
to the accessors instead so the overhead is only taken on faults.
