sfc: Generalise event generation to cover VF-owned event queues
For SR-IOV we will need to send events to event queues that belong to
VFs serviced by other drivers. Change the parameters of
efx_generate_event() to allow this and declare it extern.
While we're at it, remove the existing declaration under the wrong
name efx_nic_generate_event().
