block: make scsi_request and scsi ioctl support optional
We only need this code to support scsi, ide, cciss and virtio. And at least for virtio it's a deprecated feature to start with. This should shrink the kernel size for embedded device that only use, say eMMC a bit. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com>

Subsystems will normally enable this if needed. Users will not
normally need to manually enable this.
