xfrm: Allow transport-mode states with AF_UNSPEC selector
xfrm state selectors are matched against the inner-most flow
which can be of any address family. Therefore middle states
in nested configurations need to carry a wildcard selector in
order to work at all.
However, this is currently forbidden for transport-mode states.
Fix this by removing the unnecessary check.
