audio: Update call state from RIL during silent mode

 -In silent mode, after call is rejected from Far end, RIL
  sets call state to active to play the network message and
  sets the call_state to inactive later without informing
  the telephony framework.So, setMode() is not called from
  framework.
 -Currently,we are updating call state only if there is any
  active call or call state being set from RIL is "active".
  Fix is to update the call state when inactive state is
  received from RIL for the same VSID
