[PATCH 6.1 020/473] fs/ntfs3: Break dir enumeration if directory contents error

From: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

commit 302e9dca8428979c9c99f2dbb44dc1783f5011c3 upstream.

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.
