iio: accel: adxl367: Fix handled initialization in adxl367_irq_handler()

Clang warns:

  drivers/iio/accel/adxl367.c:887:2: error: variable 'handled' is uninitialized when used here [-Werror,-Wuninitialized]
          handled |= adxl367_push_event(indio_dev, status);
          ^~~~~~~
  drivers/iio/accel/adxl367.c:879:14: note: initialize the variable 'handled' to silence this warning
          bool handled;
                      ^
                       = 0
  1 error generated.

This should have used '=' instead of '|='; make that change to resolve
the warning.
