port-probe: retry icera probing up to 3 times, with some time in between cmds
Icera-based modems need to return a correct response to the AT%IPSYS? command,
so that they are properly detected as being Icera-based.
Now, some modems, like the Nokia 21M-02, don't seem to return a correct response
to AT%IPSYS just after being plugged in. So, setup a retry mechanism (3 retries,
with 2 seconds between retries) to try to cope with this issue.
