[dpdk-dev] [PATCH 1/2] app/testpmd: fix csumonly mode when run without outer chksum

Donot use outer metadata when neither outer ip checksum nor
outer udp checksum is enabled. PMD's will ignore the
outer_l2_len and outer_l3_len in cases where none of
the outer checksum is enabled and hence only l2_len and
l3_len will be used to calculate the offsets for L2 or L3
header.
