[rilmodem][WIP] Enabling showing of real call info already in dial response

There is not much real information coming in response to RIL_REQUEST_DIAL.
Call id, call type etc needs to be asked from modem. After this change
dial will not return before we have some real information about starting
MO call

Request for pulling delay for dial return to main branch
