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:
