Subject: RDMA/mlx5: Use proper spec flow label type
Patch-mainline: v4.17-rc7
Git-commit: 37da2a03c036538a5a79766d74bfcf5b873e5cad
References: bsc#1046305 FATE#322943

Flow label is defined as u32 in the in ipv6 flow spec, but
used internally in the flow specs parsing as u8. That was
causing loss of part of flow_label value.

Fixes: 2d1e697e9b716 ('IB/mlx5: Add support to match inner packet fields')
