[ Upstream commit 658015167a8432b88f5d032e9d85d8fd50e5bf2c ]
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.
