    udp_var: correct intoudpcb macro unintended identifier dependency
    
    Change 483fe9651 embedded struct inpcb into struct udpcb and updated the
    intoudpcb macro to use __containerof to locate it. This change accidentally
    introduced a dependency on the identifier inp being defined in the block the
    macro is expanded in. This should have been the macro argument ip. This change
    makes this simple correction.
    
    No functional change intended.
