The address of fp->path_name could be unaligned since seeking into the device path buffer for a given node could end in byte boundary. The fix is allocating aligned buffer by grub_malloc for holding the UTF16 string copied from fp->path_name, and after using that buffer as argument for grub_utf16_to_utf8 to convert it to UTF8 string.
