  net/mlx5: fs, an FTE should have no dests when deleted (2022-05-02 21:21:16 -0700)

----------------------------------------------------------------
mlx5-updates-2022-05-02

1) Trivial Misc updates to mlx5 driver

2) From Mark Bloch: Flow steering, general steering refactoring/cleaning

An issue with flow steering deletion flow (when creating a rule without
dests) turned out to be easy to fix but during the fix some issue
with the flow steering creation/deletion flows have been found.

The following patch series tries to fix long standing issues with flow
steering code and hopefully preventing silly future bugs.

  A) Fix an issue where a proper dest type wasn't assigned.
  B) Refactor and fix dests enums values, refactor deletion
     function and do proper bookkeeping of dests.
  C) Change mlx5_del_flow_rules() to delete rules when there are no
     no more rules attached associated with an FTE.
  D) Don't call hard coded deletion function but use the node's
     defined one.
  E) Add a WARN_ON() to catch future bugs when an FTE with dests
     is deleted.
