f2fs: add comment for conditional compilation statement

Commit af033b2aa8 ("f2fs: guarantee journalled quota data by checkpoint")
added function is_journalled_quota() in f2fs.h, but it located outside of
_LINUX_F2FS_H macro coverage, it has been fixed with commit 0af725fcb7
("f2fs: fix wrong #endif").

But anyway, in order to avoid making same mistake latter, let's add single
line comment to notice which #if the last #endif is corresponding to.
