eapol: Store protocol version in eapol_sm
...
Instead of one global protocol_version, we now store it inside eapol_sm.
This allows us to use the same protocol version for our response as the
request from the authenticator.
For unit tests where we had protocol version mismatches, a new method is
introduced to explicitly set the protocol version to use.

eapol: Remove user_data from __eapol_rx_packet args
...
Instead of passing the user_data parameter in every __eapol_rx_packet
call to be used by EAPOL in all tx_packet calls, add
eapol_sm_set_tx_user_data function that sets the value of user_data for
all subsequent tx_packet calls. This way tx_packet can be called from
places that are not necessarily inside an __eapol_rx_packet call.
