scsi: scsi_debug: Fix hrtimer support for ndelay

Browse Source 
[ Upstream commit 6918141d815acef056a0d10e966a027d869a922d ]

Since commit 771f712ba5 ("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.

Fixes: 771f712ba5 ("scsi: scsi_debug: Fix cmd duration calculation")
