[net PATCH 0/2] ipv4: Fix memory leaks and reference issues in fib

This series fixes one major issue and one minor issue in the fib tables.

The major issue is that we had lost the functionality that was flushing the
local table entries from main after we had unmerged the two tries.  In
order to regain the functionality I have performed a partial revert and
then moved the functionality for flushing the external entries from main
into fib_unmerge.

The minor issue was a memory leak that could occur in the event that we
weren't able to add an alias to the local trie resulting in the fib alias
being leaked.
