iio: stk3310: Don't return error code in interrupt handler

Interrupt handlers must return one of the irqreturn_t values. Returning a
error code is not supported.

The stk3310 event interrupt handler returns an error code when reading the
flags register fails.

Fix the implementation to always return an irqreturn_t value.

Fixes: 3dd477acbdd1 ("iio: light: Add threshold interrupt support for STK3310")
