Jan Kara a682414980 udf: Fix uninitialized array access for some pathnames
[ Upstream commit 028f6055c9 ]

For filenames that begin with . and are between 2 and 5 characters long,
UDF charset conversion code would read uninitialized memory in the
output buffer. The only practical impact is that the name may be prepended a
"unification hash" when it is not actually needed but still it is good
to fix this.
