Fix GSM permanent failure handling.

Wait until all APN's have been tried before checking for permanent errors
and then, don't do retires only if all of the APN's had permanent errors.

Also, don't disable the requested apn type because if we do we won't
be able to setup data because there won't be an apn type.

This was tested by creating a new non existent APN, I chose:
  Name="badapn1"
  APN="badapn1"
  Server="noapn.com"

Then selecting "badapn1" will cause a permanent error.
