vsock: remove dev_hold() and dev_put() in __vsock_deliver_tap_skb()

Browse source

__vsock_deliver_tap_skb() is called from vsock_deliver_tap()
under rcu_read_lock().

dev_queue_xmit() does not require the caller to hold a device reference
count, and the device lifetime is already protected by RCU.

Remove the redundant dev_hold(dev) and dev_put(dev) calls.
