We can simplify the interface to ipa_table_init_add() by passing two flags to it instead of the opcode and both hashed and non-hashed memory region IDs. The "filter" and "ipv6" flags are sufficient to determine the opcode to use, and with ipa_table_mem() can look up the correct memory region as well. It's possible to not have hashed tables, but we already verify the number of entries in a filter or routing table is nonzero. Stop assuming a hashed table entry exists in ipa_table_init_add().
