[PATCH 3/3] staging: iio: ad9834: use sysfs_emit() in show functions

[Gabriel Rondon <grondon@gmail.com>]

Replace sprintf() with sysfs_emit() in sysfs attribute show functions.
sysfs_emit() is the preferred API for sysfs callbacks as it is aware
of the PAGE_SIZE buffer limit. No functional change.
