    Adjust function definitions in pf.c to avoid clang 15 warnings
    
    With clang 15, the following -Werror warnings are produced:
    
        sys/netpfil/pf/pf.c:985:19: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        pf_mtag_initialize()

        sys/netpfil/pf/pf.c:995:14: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]

    This is because pf_mtag_initialize(), pf_initialize(),
    pf_mtag_cleanup(), pf_cleanup(), pf_purge_expired_src_nodes(), and
    pf_purge_unlinked_rules() are declared with (void) argument lists, but
    defined with empty argument lists. Make the definitions match the
    declarations.
