    linux-yocto/4.12: ide:ide-cd: fix kernel panic resulting from missing scsi_req_init
    
    Integrating a backport of upstream commit:
    
        ide:ide-cd: fix kernel panic resulting from missing scsi_req_init
    
        commit 79d73346ac05bc31 upstream
    
        Since we split the scsi_request out of struct request, while the
        standard prep_rq_fn builds 10 byte cmds, it missed to invoke
        scsi_req_init() to initialize certain fields of a scsi_request
        structure (.__cmd[], .cmd, .cmd_len and .sense_len but no other
        members of struct scsi_request).
    
        An example panic on virtual machines (qemu/virtualbox) to boot
        from IDE cdrom:
        ...
