i40evf: add missing rtnl_lock() around i40evf_set_interrupt_capability

Browse source 
The function calls netif_set_real_num_(tx|rx)_queues, both of which
should be done only under rntl lock. Unfortunately the
i40evf_init_task did not hold the rtnl_lock as necessary. This patch
adds the locking needed.
