wifi: b43legacy: Use flexible array for DMA metadata

Browse source

Store the per-descriptor metadata in the DMA ring allocation instead of
allocating it separately.

This ties the metadata lifetime directly to the ring, removes a separate
allocation failure path, and keeps the descriptor count available for
__counted_by() bounds checking.
