[PATCH V2 4/4] net/mlx5/hws: allow different types in miss validation

[Ophir Munk]

In validating Jump from group A to default miss group B DPDK requests
that both groups types will be identical. In practice jumping from
FDB_UNIFIED to FDB_RX or FDB_TX group types (or vice versa) is allowed.
This commit enables this jumping between the different types.

Fixes: b81f95ca770d ("net/mlx5/hws: support default miss table")
