This patch fixes outer_l3_len parse error when
PKT_TX_OUTER_IP_CKSUM is not set, which does not affect
checksum function, just be consistent with mbuf meta
information description.
The outer_l3_len is calculated wrong because 'vlan_hdr' is calculated
wrong, 'vlan_hdr' fixed and code refactored.
Fixes: 8c8b61234f ("net/hinic: refactor checksum functions")
