idpf: link NAPIs to queues

Add the missing linking of NAPIs to netdev queues when enabling
interrupt vectors in order to support NAPI configuration and
interfaces requiring get_rx_queue()->napi to be set (like XSk
busy polling).

As currently, idpf_vport_{start,stop}() is called from several flows
with inconsistent RTNL locking, we need to synchronize them to avoid
runtime assertions. Notably:

* idpf_{open,stop}() -- regular NDOs, RTNL is always taken;
* idpf_initiate_soft_reset() -- usually called under RTNL;
* idpf_init_task -- called from the init work, needs RTNL;
* idpf_vport_dealloc -- called without RTNL taken, needs it.

Expand common idpf_vport_{start,stop}() to take an additional bool
telling whether we need to manually take the RTNL lock.
