hwmon: replace snprintf in show functions with sysfs_emit

Browse source 
coccicheck complains about the use of snprintf() in sysfs
show functions.

drivers/hwmon/ina3221.c:701:8-16: WARNING: use scnprintf or sprintf

This results in a large number of patch submissions. Fix it all in
one go using the following coccinelle rules. Use sysfs_emit instead
of scnprintf or sprintf since that makes more sense.

While at it, remove unnecessary braces and as well as unnecessary
else after return statements to address checkpatch warnings in the
resulting patch.
