Subject: [PATCH 3/4] SAP: Fix handling ongoing call

If device is in ongoing call SAP server shall
response on connect with connection status 0x04
and once call is ended shall send reset status
indication.

With this patch, when reset status indication
comes from backend and SAP server is in connection
in progreess state, SAP server changes state to connected.
