AVRCP: Keep the device in the map on disconnect
Fixes a stack crash when disconnecting AVRCP
If an AVRCP connection, established by AVRC_OPEN_IND_EVT, is disconnected
by calling DisconnectDevice() in Connection Handler, there is a corner
case that does not clear Connection Control Block (CCB) entirely of a
opened handle.
So when there is re-connection trials, partially cleared CCBs causes
a critical stack crash.
When calling DisconnectDevice() in Connection Handler, there are issues.
-Keeping removed CCB info partially, such as member variable "allocated",
even though receiving AVRC_CLOSE_IND_EVT followed by clearing
Link Control Block (LCB).
-Keeping remote device address in feature_map_
This commit fixes the issue of above scenario, by keeping handle in
device_map_ and removing to send disconnected notification
when calling DisconnectDevice().
So when receiving AVRC_CLOSE_IND_EVT, normal procedure is conducted.
Note that AVRC_CLOSE_IND_EVT is occurred by both
AVCT_DISCONNECT_IND_EVT and AVCT_DISCONNECT_CFM_EVT.
And when calling avrc_->Close() in DisconnectDevice(), it just requests
to unbind LCB instead of dealloc CCB.
And when receiving AVRC_CLOSE_IND_EVT avrc_->Close() dealloc CCB.
