broadband-modem-mbim: account for race condition in quick hot swap case

Browse Source 
On MBIM modems, when the SIM is ejected and re-inserted in a quick manner,
the state machine logic encounters a race condition and eventually, the
modem response for subscriber status is ignored. This change accounts
for that state transition without erroring out.

Fixes #672.
