[PATCH] iio: hid-sensors: trigger: use no_action for non-interrupt trigger

[David Lechner]

Use the no_action special function to indicate that we aren't actually
using the interrupt for the trigger registered in hid-sensor-trigger.c.

Due to recent changes in the irq subsystem, we are now getting a warning
about a threaded interrupt being registered with only a handler for the
top half.
