In function cmd_set_mplsogre_encap_parsed(), MPLS label value was
set in mplsogre_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
mplsogre_encap_conf struct, so it is correctly copied to
rte_flow_item_mpls struct.
Fixes: 3e77031be855 ("app/testpmd: add MPLSoGRE encapsulation")

The mask of all valid bits set to 1 is redundant.
After <<12 the 20 valid bits are not changed, and the other 12 bits are set to 0.
