[PATCH] accel/qaic: initialize ret variable to 0

[Tom Rix]

clang static analysis reports
drivers/accel/qaic/qaic_data.c:610:2: warning: Undefined or garbage
  value returned to caller [core.uninitialized.UndefReturn]
        return ret;
        ^~~~~~~~~~

The ret variable is only set some of the time but is always returned.
So initialize ret to 0.
