datapath: Enforce mutual exclusion between bridge and brcompat_mod.
		
In kernels 2.6.36, Open vSwitch can (and does) safely coexist with the
Linux bridge module, but it does not make sense to load both bridge and
brcompat_mod at the same time.  Until now, nothing has prevented both from
loading; when they both load, confusion (at best) results.  This fixes
the problem by enforcing mutual exclusion.

Bug #9226.
Launchpad bug #917309.
