fs/ntfs3: Delete duplicate condition in ntfs_read_mft()

[ Upstream commit 6580151 ]

There were two patches which addressed the same bug and added the same
condition:

commit 6db6208 ("fs/ntfs3: Validate data run offset")
commit 887bfc5 ("fs/ntfs3: Fix slab-out-of-bounds read in run_unpack")

Delete one condition.
