[PATCH] jffs2: do not use C++ style comments in uapi header

[Masahiro Yamada]

Linux kernel tolerates C++ style comments these days. Actually, the
SPDX License Identifier for .c files uses C++ comment style.

On the other hand, uapi headers are strict, where the C++ comment
style is banned.

Looks like these lines are temporarily commented out, so I did not
use the block comment style.

Having said that, they have been commented out since the pre-git era.
(so, at least 14 years). 'Maybe later' may not happen. Alternative fix
might be to delete these lines entirely.

Richard's POV on the question would be interesting but mine would be to
simple drop these lines.
