KVM: arm/arm64: vgic-its: Fix restoration of unmapped collections
commit 8c58be34494b7f1b2adb446e2d8beeb90e5de65b upstream.
Saving/restoring an unmapped collection is a valid scenario. For
example this happens if a MAPTI command was sent, featuring an
unmapped collection. At the moment the CTE fails to be restored.
Only compare against the number of online vcpus if the rdist
base is set.
