    ggc: Fix up ggc_internal_cleared_alloc_no_dtor [PR117047]

    Apparently I got one of the !HAVE_ATTRIBUTE_ALIAS fallbacks wrong.

    It compiled with a warning:
    ../../gcc/ggc-common.cc: In function 'void*
ggc_internal_cleared_alloc_no_dtor(size_t, void (*)(void*), size_t, size_t)':
    ../../gcc/ggc-common.cc:154:44: warning: unused parameter 'size'
[-Wunused-parameter]
      154 | ggc_internal_cleared_alloc_no_dtor (size_t size, void (*f)(void *),
          |                                     ~~~~~~~^~~~
    and obviously didn't work right (always allocated 0-sized objects).

    Fixed thusly.

            * ggc-common.cc (ggc_internal_cleared_alloc_no_dtor): Pass size
            rather than s as the first argument to ggc_internal_cleared_alloc.
