KVM: PPC: Fix callback check in kvmppc_gsm_refresh_info

The kvmppc_gsm_refresh_info() function incorrectly checks for the
presence of the fill_info callback instead of refresh_info.

This can lead to:
- NULL pointer dereference if refresh_info is NULL but fill_info is present
- EINVAL return if refresh_info is present but fill_info is NULL

Fix this by checking the correct callback.
