[dpdk-dev] [PATCH 11/22] net/bnxt: fix error checking of FW commands

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

HWRM_CHECK_RESULT() checks the return value of HWRM command and returns
in case the command fails. There is no need of return value check after
HWRM_CHECK_RESULT().

Fixes: 49947a13ba9e ("net/bnxt: support Tx loopback, set VF MAC and queues drop")
