[PATCH BlueZ v2 12/14] shared/gatt-db: Fix crash in gatt_db_find_by_type

[Arman Uguray <armansito@chromium.org>]

Fixed a crash due to an invalid access in the find_by_type foreach
callback by correctly initializing the data fields to 0. The crash
happened because the same callback is used for find_by_type and
find_by_type_value and however find_by_type didn't correctly set the
value pointer to NULL.
