Remove the ipv4+ipv6 session decode functions and use generic flow
dissector to populate the flowi for the policy lookup.

Changes since RFC:

 - Drop mobility header support.  I don't think that anyone uses
   this.  MOBIKE doesn't appear to need this either.
 - Drop fl6->flowlabel assignment, original code leaves it as 0.

There is no reason for this change other than to remove code.

  xfrm: move mark and oif flowi decode into common code
  xfrm: policy: replace session decode with flow dissector
