So please shout if anyone has objections.

Since patch "mbuf: structure reorganization" the compiler complains
sometimes (in some conditions):
.../drivers/net/mlx5/mlx5_rxtx.c: In function âmlx5_rx_burstâ:
.../drivers/net/mlx5/mlx5_rxtx.c:2082:17: error: âlenâ may be used
uninitialized in this function [-Werror=maybe-uninitialized]
len is not initialised as it will be at the first segment of a received
packet, but it remains hard for the compiler to determine it.
Fixes: 9964b965ad69 ("net/mlx5: re-add Rx scatter support")
