Commit 0be6bfac62 ("qdev: Implement variable length array properties")
added the DEFINE_PROP_ARRAY() macro with the following comment:

  * It is the responsibility of the device deinit code to free the
  * @_arrayfield memory.

Commit 68fbcc344e added:

  DEFINE_PROP_ARRAY("read-only", XlnxEFuse, ro_bits_cnt, ro_bits,
                    qdev_prop_uint32, uint32_t),

but forgot to free the 'ro_bits' array. Do it in the instance_finalize
handler.
