Currently, a #GP is only injected 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.

Similar to commit 01ddcdc55e09 ("KVM: nSVM: Always inject a #GP if
mapping VMCB12 fails on nested VMRUN"), treat all failures equally.

Fixes: 8c5fbf1a7231 ("KVM/nSVM: Use the new mapping API for mapping guest memory")
