[PATCH] relay: use sizeof(size_t), not sizeof(size_t *) inrelay_create_buf()

[Jesper Juhl]

A number of size_t's is what we want to allocate memory for, not a
number of size_t pointers (at least as far as I can tell).
Now, depending on platform, sizeof(size_t *) may be >= sizeof(size_t)
so things actually work, but that's not really a portable assumption,
so let's use the value we actually mean.
