[parted-devel] [PATCH] tests: Set optimal blocks to 64 for scsi_debug devices

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.
