[PATCH AUTOSEL 6.1 17/28] fs/ntfs3: Delete duplicate condition in ntfs_read_mft()

[Sasha Levin]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ 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.
