[PATCH v2 1/3] net/txgbe: fix L2 tunnel error on flow create

[Zhang Tengfei <zhtfdev@gmail.com>]

txgbe_flow_create() continues to RSS parsing when L2 tunnel filter
add fails. An E-tag VF/PF rule cannot match RSS, so the original
error is overwritten.

Return immediately on L2 add failure, same as ntuple, ethertype and
SYN.
