[PATCH 2/3] net/nfp: remove panic usage for multisegment Tx

[Chaoyong He]

From: James Hershaw <james.hers...@corigine.com>

Remove usage of the rte_panic() function from the nfp PMD.

Update the nfp_net_nfd3_xmit_pkts() function to match the functionality
of the nfp_net_nfdk_xmit_pkts(), rather than use rte_panic()

Update the logging within both the nfp_net_nfd3_xmit_pkts() and
nfp_net_nfdk_xmit_pkts() functions to only make use of a single
log when encountering a transmission with multiple segments when
NFP_NET_CFG_CTRL_GATHER is not set, and to change the log-level to
ERR.
