Xuewei Zhang 83e32a5910 scsi: sd: Contribute to randomness when running rotational device 
Currently a scsi device won't contribute to kernel randomness when it uses
blk-mq. Since we commonly use scsi on rotational device with blk-mq, it make
sense to keep contributing to kernel randomness in these cases. This is
especially important for virtual machines.

commit b5b6e8c8d3b4 ("scsi: virtio_scsi: fix IO hang caused by automatic irq
vector affinity") made all virtio-scsi device to use blk-mq, which does not
contribute to randomness today. So for a virtual machine only having
virtio-scsi disk (which is common), it will simple stop getting randomness
from its disks in today's implementation.

With this patch, if the above VM has rotational virtio-scsi device, then it
can still benefit from the entropy generated from the disk.
