Two other potential solutions...

1) Fix the modem/fw and/or rild implementation to allow querying of 
max_cids even when the radio is off.

2) It's doubtful that the number of cids available actually changes over 
time, so it might be acceptable to add a vendor quirk and just hard-code 
the value for this modem as is done with MTK modems.  A slightly more 
conservative approach would be to do this in the query_cids callback if 
the operation fails.
