hwmon: replace snprintf in show functions with sysfs_emit
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.

identifier show, dev, attr, buf;

ssize_t show(struct device *dev, struct device_attribute *attr, char *buf)

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