staging: r8188eu: use mgmt to set the action codes

Use the mgmt structure in issue_action_BA to set the action codes.
We have to distinguish between the different message types.

We also have to increment the packet length manually as we're no longer
calling rtw_set_fixed_ie, which increments the length.
