[PATCH 10/11] attrib-server: Remove attrib_server_exit/attrib_server_exit functions

[Santiago Carot-Nemesio <sancane@gmail.com>]

We need neither to init nor stop gatt server whenever the demon starts
and finishes the execution, instead of doing that, we init or stop the
GATT server when the adapter is initialized or removed. Furthermore,
we don't use btd_adapter_driver any more because the GATT server must
be already initialized before any plugin use it.
