Properly notify of precise call state change after connection hangup.

When disconnecting connections via Connection.hangup(), previously no
precise call state notification was sent out.
This change should fix BT headsets ringing indefinitely after a
blacklisted call came in, as BluetoothPhoneService can now update the
headset state properly.

HTCQualcommRIL: fix data drops when switching state

* HTC RIL always throws this exception after the initial data call
  setup, so only switch ifname if the call goes from active to inactive.
* Prevents data drop due to empty address/DNS/gateway when radio tech
  switches to/from LTE/3G/2G.
