bridge: Partially disable netpoll support
The new netpoll code in bridging contains use-after-free bugs
that are non-trivial to fix.
This patch fixes this by removing the code that uses skbs after
they're freed.
As a consequence, this means that we can no longer call bridge
from the netpoll path, so this patch also removes the controller
function in order to disable netpoll.
