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:
    ...
