qmimodem: fix QMI notification messages handling

QMI notification messages handlers are never called on MC7430 without this fix.

- Do not test transaction id before calling notification handler.  On MC7430,
notification messages contain a not null transaction id (starts with 1,
increased at each message for a particular client).
- On MC7304 transaction id in notification messages is always 0.
