zeroplus-logic-cube: Fix an issue when changing triggers.

Changing triggers (e.g. from low to high) would sometimes cause the
acquisition to seemingly "hang" due to missing variable initializations
(in reality the device would wait for incorrect triggers and/or on
incorrect channels).

This fixes bug #1535.
