[PATCH 3/3] app/testpmd: compact RSS flow type output in port info

[Ferruh Yigit <ferruh.yigit@xilinx.com>]

In port info command output, 'show port info all', supported RSS flow
types printed one type per line, and although this information is not
most important part of the command it takes big part of the command
output.

Compacting the supported RSS flow type output by printing 6 (hardcoded
value) items per line, instead of one per line. Output becomes as
following:

 Supported RSS offload flow types:
   ipv4  ipv4-frag  ipv4-tcp  ipv4-udp  ipv4-sctp  ipv4-other
   ipv6  ipv6-frag  ipv6-tcp  ipv6-udp  ipv6-sctp  ipv6-other
   l2-payload  ipv6-ex  ipv6-tcp-ex  ipv6-udp-ex  port  vxlan
   geneve  nvgre  mpls
