[PATCH 03/15] net/dpaa2: fix L3/L4 csum results in packet parse

[Prashant Gupta <prashant.gupta_3@nxp.com>]

From: Brick Yang <brick.yang@nxp.com>

Layer3 and layer4 checksum validation and error
status is part of word1 of annotation area, but
driver is looking into wrong word.
This patch fixes the checksum error status in packet
parsing.

Fixes: 94d31549c380 ("net/dpaa2: support Rx checksum offload in slow parsing")
