Subject: tests: Set optimal blocks to 64 for scsi_debug devices
For: upstream code
Patch-mainline: v3.3
Git-commit: da36186cb4c2c0470a6490aed424a8d51a2b1085

The Linux kernel 4.5 changed the optimal blocks count from 64 to 1024
This causes tests using scsi_debug devices to fail because of alignment
issues. Set the opt_blks to 64 so that we have consistent behavior
across kernels.
