Fix IV_PLAT_VER and UV_ variables sent without push-peer-info

Fix IV_PLAT_VER and UV_ variables sent without push-peer-info

Commit 8c72d7981 changed the push_peer_info_detail to have an
additional level for P2P NCP and shifting most of the other levels
with 1. The check for UV_ and IV_PLAT_VER was not changed accordingly.
