staging:iio:meter: Replaces IIO_DEV_ATTR_CH_OFF by IIO_DEVICE_ATTR

The macro IIO_DEV_ATTR_CH_OFF is a wrapper for IIO_DEVICE_ATTR, with a
tiny change in the name definition. This extra macro does not improve
the readability and also creates some checkpatch errors.

This patch fixes the checkpatch.pl errors:
