[PATCH v2] fs/ntfs3: Break dir enumeration if directory contents error

[Konstantin Komarov]

If we somehow attempt to read beyond the directory size, an error
is supposed to be returned.

However, in some cases, read requests do not stop and instead enter
into a loop.

To avoid this, we set the position in the directory to the end.
