io: accel: kxcjk-1013: Fix iio_event_spec direction

Because IIO_EV_DIR_* are not bitmasks but enums,
IIO_EV_DIR_RISING | IIO_EV_DIR_FALLING is not equal
with IIO_EV_DIR_EITHER.

This could lead to potential misformatted sysfs attributes
like:
	* in_accel_x_thresh_(null)_en
	* in_accel_x_thresh_(null)_period
	* in_accel_x_thresh_(null)_value

or even memory corruption.
