iio: ina2xx-adc: sysfs_emit()
sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it
knows about the sysfs buffer specifics and has some built-in checks for
size and alignment.
Use sysfs_emit() to format the custom `in_allow_async_readout` device
attribute of the ina2xx-adc driver.
