KVM: arm/arm64: vgic-its: Fix vgic_its_restore_collection_table returned value



vgic_its_restore_cte returns +1 if the collection table entry
is valid and properly decoded. As a consequence, if the
collection table is fully filled with valid data that are
decoded without error, vgic_its_restore_collection_table()
returns +1. This is wrong.

Let's return 0 in that case.
