[PATCH net v3] octeon_ep_vf: Resolve netdevice usage count issue

[Sathesh B Edara]

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. Therefore, netdev_hold and netdev_put have been removed.

Fixes: cb7dd712189f ("octeon_ep_vf: Add driver framework and device initialization")
