This patch changes BR/EDR behavior. When GATT device driver is probed,
or a SDP search finds a GATT record, a second discovery via GATT is
started.
This patch is for testing purposes only; the GATT spec states that
this is not the correct behavior for dual-mode. Services that are
to be exposed in LE and BR/EDR shall have SDP records of their own,
as well, so GATT discovery is not needed.
