It is indeed unused so remove it.

I went back to the original patches to see if this was ever used;
since v2 (when the ntfs3 driver was split up) it was not. I triple
checked the v1 as well.
v2: https://lore.kernel.org/lkml/[email protected]/
v1: https://dl.paragon-software.com/ntfs3/ntfs3.patch
I don't think there's a logic error here.

Looks like it was used for debugging or way before index_find_raw()
needed hint or something. So this should be ok.
