Jan Kara 5c90d03628 udf: Verify symlink size before loading it 
commit a1d47b2629 upstream.

UDF specification allows arbitrarily large symlinks. However we support
only symlinks at most one block large. Check the length of the symlink
so that we don't access memory beyond end of the symlink block.
