validate_add_rxsa() did not originally contain that requirement.
It does exist in validate_add_txsa(), which means that providing a PN
is necessary only when creating TXSA.
When creating an RXSA without providing a PN it will be set to 1
(init_rx_sa+15).
This is the original behavior which of course can be changed.
