[PATCH] ntfs3: initialize err in attr_wof_frame_info

[Ruoyu Wang]

attr_wof_frame_info() may reuse a cached offsets folio. In that case the
loop can fill the output offsets without calling attr_load_runs_range()
or ntfs_read_run(), leaving err uninitialized before the common return
path. Initialize err to 0 for the successful cached path.
