Revert "net/mlx5e: Don't use termination table when redundant"
[ Upstream commit 081abcacaf0a9505c0d4cc9780b12e6ce5d33630 ]
This reverts commit 14624d7247fcd0f3114a6f5f17b3c8d1020fbbb7.
The termination table usage is requires for DMFS steering mode as firmware
doesn't support mixed table destinations list which causes following
syndrome with hairpin rules:
[81922.283225] mlx5_core 0000:08:00.0: mlx5_cmd_out_err:803:(pid 25977): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xaca205), err(-22)
