common: accel: Add error code for irq handler
When IRQ handler is not processing any event raised,
return NOT_HANDLED.
Without this change, any event would set the light sensor
process timestamp and, if the light sensor frequency was lower
than BM160 fifo interrupt frequency, we would never read from
the light sensor.
BRANCH=smaug
BUG=chrome-os-partner:43800
TEST=Compile. Check that light sensor data get updated.
