--------------------------------

[ Upstream commit 42330a32 ]

The nicvf_probe() won't destroy workqueue when register_netdev()
failed. Add destroy_workqueue err handle case to fix this issue.

Fixes: 2ecbe4f4 ("net: thunderx: replace global nicvf_rx_mode_wq work queue for all VFs to private for each of them.")
