net/mlx5e: Build SKB with exact frag_size
Build the SKB over the receive packet instead of the
whole page. Getting the SKB's linear data and shared_info
closer improves locality.
In addition, this opens up the possibility to make use of
other parts of the page in the downstream page-reuse patch.
Fixes: 1bfecfca565c ("net/mlx5e: Build RX SKB on demand")
