    nvme: Move bools to fill hole
    
    The two bools in nvme_request create a 6 byte hole today. Move them to
    after retires to fill the 4 byte hole there and add a spare[2] to make
    nvme_request 8 bytes smaller. spare[2] isn't strictly necessary, but
    documents how many bytes we have left in that hole, as the number of
    booleans will increase shortly.
