nested_svm_vmrun() currently only injects a #GP if kvm_vcpu_map() fails
with -EINVAL. But it could also fail with -EFAULT if creating a host
mapping failed. Inject a #GP in all cases, no reason to treat failure
modes differently.
Fixes: 8c5fbf1a7231 ("KVM/nSVM: Use the new mapping API for mapping guest memory")
