[Patch Bluez] HFP gateway: fix failure on very first GSM connection

This patch fix the very first incoming connection from a GSM device
(playing the gateway role), when 'device->gateway' is NULL (when we didn't
perform a SDP browse request yet)

we add the service with 'btd_device_add_uuid(device->btd_dev, remote_uuid)'
but we provide HFP_HS_UUID as remote_uuid. Consequently, the HFP headset
service is activated instead the gateway service.

Note: I failed to know which UUID is the good one to provide for
audio_device_request_authorization()
