arm/arm64: KVM: Take mmap_sem in kvm_arch_prepare_memory_region
commit 72f310481a08db821b614e7b5d00febcc9064b36 upstream.
We don't hold the mmap_sem while searching for VMAs (via find_vma), in
kvm_arch_prepare_memory_region, which can end up in expected failures.
Fixes: commit 8eef91239e57 ("arm/arm64: KVM: map MMIO regions at creation time")
