xfrm: Allow transport-mode states with AF_UNSPEC selector
[ Upstream commit c276a706ea1f51cf9723ed8484feceaf961b8f89 ]
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.
Fixes: 13996378e658 ("[IPSEC]: Rename mode to outer_mode and add inner_mode")
