app/testpmd: fix MPLSoUDP encapsulation

In function cmd_set_mplsoudp_encap_parsed(), MPLS label value was
set in mplsoudp_encap_conf struct without the required offset.
As a result the value was copied incorrectly into
rte_flow_item_mpls struct.

This patch sets MPLS label value in appropriate location at
mplsoudp_encap_conf struct, so it is correctly copied to
rte_flow_item_mpls struct.
