Subject: [PATCH] qeth: clean up error handling

In the functions that are registering and unregistering MAC
addresses in the qeth-handled hardware, remove callback functions
that are unnesessary, as only the return code is analyzed.
Translate hardware response codes to semi-standard 'errno'-like
codes for readability.

Add kernel-doc description to the internal API function
qeth_send_control_data().
