Public bug reported:

Ovs agent supports l2 extension framework.

But the logic process each device in a single loop[1], if any l2
extensions process a single device and failed with some unforeseeable
errors when ext_manager calls l2 extenstion. The error will be catched
in out layer and this loop will exit totally, if there still are some
devices not process, maybe the rest of devices maybe success, that no
reason to skip all of them, so this is the point to be enhanced.
