hw/nvram/xlnx-bbram: Call register_finalize_block

The TYPE_XLNX_BBRAM device creates a register block with
register_init_block32() in its instance_init method; we must
therefore destroy it in our instance_finalize method to avoid a leak
in the QOM introspection "init-inspect-finalize" lifecycle:

Direct leak of 304 byte(s) in 1 object(s) allocated from:
