[PATCH] net/mlx5: fix matcher flags in counter offset detection

[Dariusz Sosnowski]

This patch fixes a bug in
mlx5_flow_dv_discover_counter_offset_support()
uncovered by a warning reported by MSVC:

    ../drivers/net/mlx5/mlx5_flow_dv.c(19636): warning C5287:
        operands are different enum types 'ibv_flow_attr_type' and
        'ibv_flow_flags';
        use an explicit cast to silence this warning

IBV_FLOW_ATTR_FLAGS_EGRESS was incorrectly passed in to
type field of mlx5dv_flow_matcher_attr struct,
instead of flags field.
As a result counter offset support discovery returned a false positive
result on application with old rdma-core.
