[PATCH BlueZ] core/profile: Fix calling service_accept

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

service_accept shall only be used with profiles that implement .accept
callback, to set connecting state directly use service_set_connecting
which does not require .accept to be implemented.
