scsi: scsi_debug: Fix hrtimer support for ndelay
[ Upstream commit 6918141d815acef056a0d10e966a027d869a922d ]
Since commit 771f712ba5b0 ("scsi: scsi_debug: Fix cmd duration
calculation"), ns_from_boot value is only evaluated in schedule_resp()
for polled requests.
However, ns_from_boot is also required for hrtimer support for when
ndelay is less than INCLUSIVE_TIMING_MAX_NS, so fix up the logic to
decide when to evaluate ns_from_boot.
