Marc Zyngier e6c24e2d05 irqchip/gic-v4: Correctly deal with set_affinity on lazily-mapped VPEs ...

Zenghui points out that a recent change to the way set_affinity is
handled for VPEs has the potential to return an error if the VPE
hasn't been mapped yet (because the guest hasn't emited a MAPTI
command yet), affecting GICv4.0 implementations that rely on the
ITSList feature.

Fix this by making the set_affinity succeed in this case, and
return early, without trying to touch the HW.

Fixes: 1442ee0011 ("irqchip/gic-v4: Don't allow a VMOVP on a dying VPE")
