This patch fixes (dereference after null check) coverity issue.
The address of first segmented packets was not set correctly during
reassembling packets which led to this issue.

Coverity issue: 343422, 343403
Fixes: ca74903b75cf ("net/i40e: extract non-x86 specific code from vector driver")
Cc: stable@dpdk.org
