The hashtable is not freed if GRUB_AFFS_FILETYPE_HARDLINK and
grub_disk_read() failed. If grub_affs_create_node() returns non-zero
the hashtable should be freed too.
By the way, the hashtable argument is unused in grub_affs_create_node().
So, we can remove the argument and free it in grub_affs_iterate_dir().
It allocates the memory and it should be responsible for releasing it.
This is why commit ebf32bc4e9 (fs/affs: Fix resource leaks) missed
this memory leak.
