Redial on the other slot upon radio disconnect

The radio now supports the DIALED_ON_WRONG_SLOT DisconnectCause for
emergency calls. If the radio needs the emergency call to be redialed on
another slot, it will send this DisconnectCause.

This change adds the functionality to support the new DisconnectCause
and perform the redial silently in Telephony.
