iio: core: Use sysfs_emit() (trivial bits)
sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it
knows about the sysfs buffer specifics and has some built-in sanity checks.
This patch converts the places in the iio core that follow the pattern of
return s*printf(...)
to
return sysfs_emit(...)
