net/mlx5: DR, Handle reformat capability over sw-steering tables 

On flow table creation, send the relevant flags according to what the FW
currently supports.
When FW doesn't support reformat option over SW-steering managed table,
the driver shouldn't pass this.

Fixes: 988fd6b32d ("net/mlx5: DR, Pass table flags at creation to lower layer")
