[PATCH obexd 1/3] Fix not responding when driver_get_headers return 0

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

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

When calling driver_get_headers it may not be ready but after the backend
respond the result can still be 0 which indicades no headers need to
added and we can start sending the body.
