[dpdk-dev] [PATCH] pdump: fix log message to display correct error number

[Reshma Pattan]

The ethdev Rx/Tx remove callback apis doesn't set rte_errno during
failures, instead they just return negative error number, so using
that number in logs instead of rte_errno upon Rx and Tx callback
removal failures.

Fixes: 278f9454 ("pdump: add new library for packet capture")
