No gps available since change to new API

With the latest version of libqmi the command mmcli -m 0 --location-get prints an empty output for nmea. I was able to trace back the issue to commit 0e5ae24b. My investigations show that with the old code the call to qmi_utils_read_guint16_from_buffer on line 478 of qemu-proxy.c puts error_status to 0, while in the new code the call to qmi_message_tlv_read_guint16 on line 482 puts error_status to values around 32500-32700 (it varies between runs of qmi-proxy but is constant for every call to track_cid in a single run of qmi-proxy). I have a sierra gobi 3000 modem. Please let me know if you need more imformation.
