Subject: scsi: scsi_debug: write_same: fix error report

From: Douglas Gilbert <[email protected]>

[ Upstream commit e33d7c56450b0a5c7290cbf9e1581fab5174f552 ]

The scsi_debug driver incorrectly suggests there is an error with the SCSI WRITE SAME command when the number_of_logical_blocks is greater than 1. It will also suggest there is an error when NDOB (no data-out buffer) is set and the number_of_logical_blocks is greater than 0. Both are valid, fix.
