Retry authentication in key-missing or pairing collision use case

Problem:
A2DP connection failing with connection timeout

Steps:
1. Pair and connect car kit from DUT
2. Disconnect the car kit from DUT
3  Unpair DUT from car kit menu and initiate pairing from car kit.
   Pairing and A2DP connection should be successful.

Failure:
Paring and A2DP connections fail

Root Cause:
As the stack posting authentication failure to upper layers
when SOC gives key missing error code remote removed from
DUT paired list, but same time lower layers keep retrying
for missing key and leading to connection failure.

Fix:
Don't post authentication complete to upper layers when stack
re trying for security in key missing or transaction collision cases
