zebra: fix infinite loop when deleting an interface

When deleting a VLAN interface after flushing its
addresses, zebra uses 100% CPU time and freezes.

 * interface.c: The while loop in line 407 that
   should clean up connected routes never hits one
   of the 2 lines "last = node;" and thus loops
   forever.
