====================
netpoll: Cleanups and fixes

This should be a small set of safe cleanups and fixes to netpoll.

The fixes are vlan headers are now always inserted when needed, and
napi polling is always avoided when network devices are closed.

There are a bunch of little cleanups removing unnecessary code, fixing
function naming, not taking unnecessary locks and removing general
silliness.
