octeon_ep_vf: Resolve netdevice usage count issue

Browse source

[ Upstream commit 8548c84c00 ]

The netdevice usage count increases during transmit queue timeouts
because netdev_hold is called in ndo_tx_timeout, scheduling a task
to reinitialize the card. Although netdev_put is called at the end
of the scheduled work, rtnl_unlock checks the reference count during
cleanup. This could cause issues if transmit timeout is called on
multiple queues.
