[PATCH net-next 5/8] net: hdlc_ppp: fix the comments style issue

[Guangbin Huang]

From: Peng Li <lipeng321@huawei.com>

Networking block comments don't use an empty /* line,
use /* Comment...

Block comments use * on subsequent lines.
Block comments use a trailing */ on a separate line.

This patch fixes the comments style issues.

This probably reduces the readability of the code. So i would not make
this change.

Please remember these are only guidelines. Please don't blindly make
changes, or change it because some bot says so. Check that it actually
makes sense and the code is better afterwards.
