Free `cached_dir_base` to fix memory leak

The static analyzer from LLVM/Clang 1:3.4~svn194079-1 reports a memory
leak in `libdvdread/src/dvd_udf.c`.

        $ scan-build -o scan-build make
        $ scan-view scan-build/2013-11-18-155601-16168-1

The memory is allocated in

       	if((cached_dir_base = malloc(dir_lba * DVD_VIDEO_LB_LEN + 2048)) == NULL)

and has to be freed before returning from the function.
