When the mbuf data size cannot contain the maximum Rx packet length with
the mbuf headroom, a packet should be scattered in more than one mbuf.
The application did not configure scatter offload in the above case.
Enable the Rx scatter offload in the above case.
Fixes: 33f9630fc23d ("app/testpmd: create mbuf based on max supported segments")
