    Adjust svc_vc_null() definition to avoid clang 15 warning
    
    With clang 15, the following -Werror warning is produced:
    
        sys/rpc/svc_vc.c:1078:12: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        svc_vc_null()
                   ^
                    void
    
    This is because svc_vc_null() is declared with a (void) argument list,
    but defined with an empty argument list. Make the definition match the
    declaration.

    (cherry picked from commit 87d18efef7e3df5f4475cfe1a8f6d6782b7c1527)
