A new feature in the dongle firmware requires a handshake during
firmware intialization. The request is sent in event packets which the
host driver is not able to handle before any net device registered.
Discard those packets as the context for handling it is missing.
The initialization handler will be added as part of feature support
code in the future.

because it did not add much functionality any longer.

The function is only called with sk_buff parameter being non-zero so
the prototype does not need to support passing a char buffer any longer.
When the function is called with a NULL sk_buff parameter it returns
-EINVAL now.
