Public bug reported:

If an ML2 type driver is disabled after segments have been allocated
using that type driver, subsequent network deletions will not remove the
DB records allocated by that type driver since the driver isn't there to
release the segment[1]. These orphaned segments will then be unavailable
for use if the type driver is re-enabled later.
