octeontx2-vf: fix workqueue and netdev race in probe/remove
Initialize the VF workqueue before register_netdev() so ndo_set_rx_mode
does not queue work on a NULL workqueue. Unregister the netdev before
destroying the workqueue, and add proper probe error cleanup.
Fixes: cbc100aa2205 ("octeontx2-nicvf: add ndo_set_rx_mode support for multicast & promisc")
