[ Upstream commit 62d2664351ef37da34f6f3a3fd8ab34257d6fe30 ]

Fix several issues in SMFS steering info dump:
- Fix outdated macro value for matcher mask in the SMFS debug dump format.
The existing value denotes the old format of the matcher mask, as it was
used during the early stages of development, and it results in wrong
parsing by the steering dump parser - wrong fields are shown in the
parsed output.
- Add the missing destination table to the dumped action.
The missing dest table handle breaks the ability to associate between
the "go to table" action and the actual table in the steering info.

Fixes: 9222f0b27da2 ("net/mlx5: DR, Add support for dumping steering info")
