KVM: arm64: Drop useless __GFP_HIGHMEM from kvm struct allocation 



A recent change on the receiving end of vmalloc() started warning about
unsupported GFP flags passed by the caller. Nathan reports that this
warning fires in kvm_arch_alloc_vm(), owing to the fact that KVM is
passing a meaningless __GFP_HIGHMEM.

Do as the warning says and fix the code.
