I don't think this does quite what you meant it to do!

I can fix it by adding the missing `=', but it may cause the kassert
to fire because I don't see anywhere in xennet_rx_free_req that sets
it to GRANT_INVALID_REF and I don't know the surrounding logic well
enough to be confident that just changing it there is correct.
