Add some word. Actually, I'd like to add:
if (!fsckcfg.extract_path)
	return;

at the beginning of erofsfsck_set_attributes() instead of
using "if (!ret && fsckcfg.extract_path)" in the caller.

So the HAVE_UTIMENSAT case needs to be resolved as well.

Btw, I have no idea why it could become unreadable to you, first,
it would avoid "mixed declarations and code" unless defining them at the
beginning of blocks, and I don't like memset(.., 0, ) and set
independently since memset generally is a library function (unless
compliers do some built-in tricks) rather than a language feature.
