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.
This patch converts the places in the IIO core that follow the pattern of
return s*printf(...)
to
return sysfs_emit(...)
This covers the new places that have been introduced where sprintf() is
used for formatting sysfs output since the last time this was done in
commit
83ca56b663cf ("iio: core: Use sysfs_emit() (trivial bits)").
