fs/ntfs3: Keep runs for $MFT::$ATTR_DATA and $MFT::$ATTR_BITMAP
[ Upstream commit eb95678ee930d67d79fc83f0a700245ae7230455 ]
We skip the run_truncate_head call also for $MFT::$ATTR_BITMAP.
Otherwise wnd_map()/run_lookup_entry will not find the disk position for the bitmap parts.
Fixes: 0e5b044cbf3a ("fs/ntfs3: Refactoring attr_set_size to restore after errors")
