If I'm not missing anything, in case kvm_create_vm_debugfs fails, we
will have a memory leak due to not freeing the kvm object.
A call to kvm_put_kvm was accidentally removed from an error handling in
commit 506cfba9e726 ("KVM: don't use anon_inode_getfd() before possible failures")
This patch simply restores the call to kvm_put_kvm, so that the kvm
object is destroyed before returning an error.
