Description

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.
