iio: Fix error handling in iio_trigger_attach_poll_func
commit 99543823357966ac938d9a310947e731b67338e6 upstream.
When attaching a pollfunc iio_trigger_attach_poll_func will allocate a
virtual irq and call the driver's set_trigger_state function. Fix error
handling to undo previous steps if any fails.
In particular this fixes handling errors from a driver's
set_trigger_state function. When using triggered buffers a failure to
enable the trigger used to make the buffer unusable.
