    Adjust function definitions in if_pfsync.c to avoid clang 15 warnings
    
    With clang 15, the following -Werror warnings are produced:
    
        sys/netpfil/pf/if_pfsync.c:2439:21: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        pfsync_pointers_init()
                            ^
                             void
        sys/netpfil/pf/if_pfsync.c:2453:23: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        pfsync_pointers_uninit()
                              ^
                               void
        sys/netpfil/pf/if_pfsync.c:2503:12: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        pfsync_init()
                   ^
                    void
        sys/netpfil/pf/if_pfsync.c:2524:14: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        pfsync_uninit()
                     ^
                      void
    
    This is because pfsync_pointers_init(), pfsync_pointers_uninit(),
    pfsync_init(), and pfsync_uninit() are declared with (void) argument
    lists, but defined with empty argument lists. Make the definitions match
    the declarations.
