Problem seen with a MC7304 modem and a roaming SIM card.
Status in org.ofono.NetworkRegistration properties ends up in "registered"
instead of roaming. Both AT command and qmicli indicates we are roaming.
What's happening is the following:
1) first QMI_NAS_SS_INFO_IND indicating we are registered contains a
QMI_NAS_RESULT_ROAMING_STATUS parameter.
Parameter inside says we are roaming and qmimidem driver correctly reports
status NETWORK_REGISTRATION_STATUS_ROAMING.
2) other QMI_NAS_SS_INFO_IND arrive, saying we are registered without
QMI_NAS_RESULT_ROAMING_STATUS parameter.
Driver reports NETWORK_REGISTRATION_STATUS_REGISTERED.
Extract of traces with QMI binary debug interpreted (as far as I can...):

I can't tell if not having the ROAMING_STATUS parameter in all indication
is something happening only on MC7304 or if it happens on all "QMI" modems.
I have also seen (on MC7430, with a roaming SIM card):
- first notification indicating status
QMI_NAS_REGISTRATION_STATE_SEARCHING and roaming ON
- following notifications indicating status
QMI_NAS_REGISTRATION_STATE_REGISTERED and no roaming notification
So we must handle roaming information even when not registered.
