net: dsa: clean up dsa_user_add_cls_matchall()

The body is a bit hard to read, hard to extend, and has duplicated
conditions.

Clean up the "if (many conditions) else if (many conditions, some
of them repeated)" pattern by:

- Moving the repeated conditions out
- Replacing the repeated tests for the same variable with a switch/case
- Moving the protocol check inside the dsa_user_add_cls_matchall_mirred()
  function call.

This is pure refactoring, no logic has been changed, though some tests
were reordered. The order does not matter - they are independent things
to be tested for.
