app/crypto-perf: fix number of segments
PATCH 1/1 app/crypto-perf: fix number of segments
When segment size is provided, the total number of segments would be calculated. Segment size updates due to headroom/tailroom need to be accounted for when determining total number of segments required.
Fixes c1670ae0022b ("app/crypto-perf: honour min headroom/tailroom")
