Subject: [0/8] netpoll/bridge fixes

Hi:

Qianfeng Zhang reported that he was seeing crashes with the
attached backtrace.

I tracked this down to the recently added netpoll support in
the bridge device.  It's a classic use-after-free problem.

Trying to solve it brought out a host of other issues, some of
which existed prior to the new bridge code.  The following patches
attempt to address some of these issues.

Warning, this is completely untested (apart from compiling with
everything enabled) so please look but don't merge :)

Thanks,
