l2cap_ecred_defer_connect() clears FLAG_DEFER_SETUP also for channels
with different PID/PSM, which will not be added to the same
ECRED_CONN_REQ in any case. Consequently, only one ECRED connection
group can work at a time although it appears intended they would be
separate for each PID/PSM combination.
Fix by clearing FLAG_DEFER_SETUP only for the connections that could be
added in the request. Retain test_bit(FLAG_DEFER_SETUP) before calling
get_peer_pid as it may be NULL otherwise.
