Log:
  MFC 258591
  In vnet_route_uninit(), free some memory that is allocated in vnet_route_init().
  
  To reproduce the problem:
    (1)  Take a GENERIC kernel config, and add options for: VIMAGE, WITNESS,
         INVARIANTS.
    (2)  Run this command in a loop:
         jail -l -u root -c path=/ name=foo persist vnet && jexec foo ifconfig lo0 127.0.0.1/8 && jail -r foo
  
         see: http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021280.html
              http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021291.html
  
  This doesn't eliminate all the "Freed UMA keg was not empty" warning messages
  on the console, but it helps.
