[PATCH 1/2] telit: make sure QSS status values read are always known

Given that the MMTelitQssStatus enums are mapped directly to the
values read from the #QSS response, we need to make sure that we never
return a value for which we don't have an enum defined.
Also, use set_error() instead of the propagate_error() + error_new()
combo.
