    The scsi error handling path re-uses previously queued up (and errored-out)
    cmds. If such a re-used cmd had a data-phase then cmdinfo will have
    data_in_urb / data_out_urb still set to the free-ed urbs from the errored-out
    cmd, and they will get free-ed a second time when the error handling cmd
    completes, corrupting the kernel heap.
    
    Clearing cmdinfo on command queue-ing fixes this, and seems like a good idea
    in general.
