ip ipsec: Remove IPSec SPI-0 punt reason
Type: fix
There's no call for an SPI-0 punt reason with UDP encap, since
it's only with UDP encap that the ambiguity between IKE or IPSEC
occurs (and SPI=0 determines IKE).
Enhance the punt API to dum ponly the reason requested, so a client
can use this as a get-ID API
