    Adjust function definitions in kern_cons.c to avoid clang 15 warnings
    
    With clang 15, the following -Werror warnings are produced:
    
        sys/kern/kern_cons.c:201:14: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        cninit_finish()
                     ^
                      void
        sys/kern/kern_cons.c:376:7: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        cngrab()
              ^
               void
        sys/kern/kern_cons.c:389:9: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        cnungrab()
                ^
                 void
        sys/kern/kern_cons.c:402:9: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        cnresume()
                ^
                 void
    
    This is because cninit_finish(), cngrab(), cnungrab(), and cnresume()
    are declared with (void) argument lists, but defined with empty argument
    lists. Make the definitions match the declarations.
    
    MFC after:      3 days
    
    (cherry picked from commit 9806e82a23924f32dc5976bc8687fbbe293a140b)
