    thunderbolt: Fix INVARIANTS compilation
    
    The problem is that THUNDERBOLT_DEBUG triggers the use of some
    variables, but it is independent of INVARIANTS and the variables it uses
    were tagged with '__diagused'.
    
    Fix this by using '__maybe_unused' in those places.
    
    Fixes:          183633079178 ("thunderbolt: make code -Wunused clean")
    Fixes:          886164895f3f ("amd64: complete thunderbolt KERNCONF integration")
