There were two patches which addressed the same bug and added the same
condition:
commit 6db620863f85 ("fs/ntfs3: Validate data run offset")
commit 887bfc546097 ("fs/ntfs3: Fix slab-out-of-bounds read in run_unpack")
Delete one condition.

I deleted this one because it was further away from the "roff = "
assignement.
