Subject: [PATCH] Adjust ng_{name,ID}_rehash() definitions to avoid clang 15
 warnings

With clang 15, the following -Werror warnings are produced:

    sys/netgraph/ng_base.c:981:15: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    ng_name_rehash()
                  ^
                   void
    sys/netgraph/ng_base.c:1012:13: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    ng_ID_rehash()
                ^
                 void

This is because ng_name_rehash() and ng_ID_rehash() are declared with
(void) argument lists, but defined with empty argument lists. Make the
definitions match the declarations.
