ARM: KVM: Unmap IPA on memslot delete/move
commit df6ce24f2ee485c4f9a5cb610063a5eb60da8267 upstream.
Currently when a KVM region is deleted or moved after
KVM_SET_USER_MEMORY_REGION ioctl, the corresponding
intermediate physical memory is not unmapped.
This patch corrects this and unmaps the region's IPA range
in kvm_arch_commit_memory_region using unmap_stage2_range.
