fs/ntfs3: Break dir enumeration if directory contents error

Browse Source 
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.
