KVM: PPC: Book3S HV nestedv2: Fix an error handling path in gs_msg_ops_kvmhv_nestedv2_config_fill_info()

The return value of kvmppc_gse_put_buff_info() is not assigned to 'rc' and
'rc' is uninitialized at this point.
So the error handling can not work.

Assign the expected value to 'rc' to fix the issue.
