[PATCH BlueZ] core: Fix not forwarding errors caused by SDP search properly

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

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

In case bt_search_service fails while processing (e.g. connection is
dropped) the error forward is a positive value leading
btd_service_connecting_complete to not change any state at all.

Futhermore the error from sdp_process was completely ignored which may
cause problems as well.
