Marks successfuly allocated channel during incoming connection
request to dedicated channel context flag. Introduced here ACCEPTOR
role on L2CAP layer helps then resolve channel CoC state context when
incoming connection setup is deferred by changed security on GAP caused
by local L2CAP channel requirement.
