iio: max31865: 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 ``in_filter_notch_center_frequency`
and fault_ovuv` device attributes of the max31865 driver.
