While fixing a recent issue I noticed that we are doing some unnecessary
work inside the loop for ip_fib_net_exit. As such I am pulling out the
initialization to NULL for the locally stored fib_local, fib_main, and
fib_default.
In addition I am restoring the original code for flushing the table as
there is no need to split up the fib_table_flush and hlist_del work since
the code for packing the tnodes with multiple key vectors was dropped.
