iio: scd4x: Use 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 `calibration_auto_enable` device
attribute of the scd4x driver.
