[dpdk-dev] [PATCH v2] net/mlx5: revert default rules amount optimization

This reverts commit 304ffe576f239e5405228c0feec04b6138d525b7.

It tried to optimize the amount of the default flow
rules and created it only once on top of the PF representor.

For each FDB rule, the default port ID to match on is like of the port
that triggers the flow.

Hence, the single default rule will not be matched on the VF traffic.

As a result, all the traffic of the VFs will not match to the jump flow
in the root table and will always be forwarded to the representor port.

Revert the commit.
