flex_array: allow 0 length elements
flex_arrays are supposed to be a replacement for: kmalloc(num_elements * sizeof(element)) If kmalloc is given 0 num_elements or a 0 size element it will happily return ZERO_SIZE_PTR. Which looks like a valid allocation, but which will explode if something actually try to use it. The current flex_array code will return an equivalent result if num_elements is 0, but will fail to work if sizeof(element) is 0. This patch allows allocation to work even for 0 size elements. It will cause flex_arrays to explode though if they are used. Imitating the kmalloc behavior.
