[dpdk-dev] [PATCH 12/15] net/bnxt: fix to check for invalid VNIC in cleanup path

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

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

The cleanup/rollback operation post rte_eth_dev_start failure might end
up invoking an HWRM cmd even on an invalid vNIC resulting in error
messages being logged needlessly.
Fix to check for the same before issuing the HWRM cmd.

Fixes: c09f57b49c13 ("net/bnxt: add start/stop/link update operations")
