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

This doesn't eliminate all the "Freed UMA keg was not empty" warning messages
on the console, but it helps.
