Subject: [PATCH] net/octeontx: fix stop clearing Rx/Tx functions

[ upstream commit efb9dd148e234aecd01966cd1d2aaa4b75836966 ]

On dev_stop the Rx/Tx_burst functions are being set to NULL, this causes
a SEGFAULT in cases where control path calls stop and a paket is still
being processed by a worker.
Instead clear the fastpath functions in dev_close.

Fixes: da6c687471a3 ("net/octeontx: add start and stop support")
