Christophe JAILLET 801aee63e5 KVM: PPC: Book3S HV nestedv2: Fix an error handling path in gs_msg_ops_kvmhv_nestedv2_config_fill_info() 
[ Upstream commit b52e8cd3f835869370f8540f1bc804a47a47f02b ]

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.

Fixes: 19d31c5f1157 ("KVM: PPC: Add support for nestedv2 guests")
