[PATCH] KVM: arm64: vgic: Remove duplicate check in update_affinity_collection()

[Gavin Shan]

The ITS collection is guranteed to be !NULL when update_affinity_collection()
is called. So we needn't check ITE's collection with NULL because the
check has been included to the later one.

Remove the duplicate check in update_affinity_collection().
