This patch converts some basic cases of ethtool_sprintf() to
ethtool_puts().

The conversions are used in cases where ethtool_sprintf() was being used
with just two arguments:
|       ethtool_sprintf(&data, buffer[i].name);
or when it's used with format string: "%s"
|       ethtool_sprintf(&data, "%s", buffer[i].name);
which both now become:
|       ethtool_puts(&data, buffer[i].name);
