DTX: add flag for AMR HR P*
Add flag to explicitly track the state of DTX DL for AMR HR whe SID_FIRST_P1 has been sent to L1 already but no next frame available yet: this can be followed by SID_FIRST_P2 or SID_FIRST_INH depending on arrival of voice frame within next 60 ms. Change-Id: Id28b07b8e83cfe5e84de48a2f124084036580cd4
