ipv4: Do not allow MAIN to be alias for new LOCAL w/ custom rules
In the case of custom rules being present we need to handle the case of the LOCAL table being intialized after the new rule has been added. To address that I am adding a new check so that we can make certain we don't use an alias of MAIN for LOCAL when allocating a new table.
