Subject: [PATCH 09/13] staging: r8188eu: clean up on_action_public

Use the struct mgmt to read the action_code. This is much simpler than
parsing the message ourselves.

Add a comment about reading the action code. All members of the action
enum start with an action_code byte. It does not matter which member we
use.
