Currently in otx2_open on failure of nix_lf_start
transmit queues are not stopped which are already
started in link_event. Since the tx queues are not
stopped network stack still try's to send the packets
leading to driver crash while access the device resources.
Fixes: 50fe6c02e ("octeontx2-pf: Register and handle link notifications")
