Shouldn't return -EINVAL here, similar to what
pkt_session_set_property_1x() does for unknown property?

nit: How about simply return pkt_session_set_property_3xx(pkt, cookie,
ptype, pdata); and removing the |ret| variable completely, since the return
below the switch can just return 0 all the time?

nit: Since we're adding third variant, I'd consider using function pointers
here, but no strong opinion.
