scsi: add a scsi_alloc_request helper
Add a new helper that calls blk_get_request and initializes the scsi_request to avoid the indirect call through ->.initialize_rq_fn. Note that this makes the pktcdvd driver depend on the SCSI core, but given that only SCSI devices support SCSI passthrough requests that is not a functional change.
