net/mlx5: support mbuf headroom for LRO packet
Patch [1] zeroes the mbuf headroom when the port is configured with LRO because when working with more than one stride per packet the HW cannot guaranty an headroom in the start stride of each packet. Change the solution to support mbuf headroom by adding an empty buffer as the first packet segment, scatter mode must be enabled to support it.
