Reset EAPOL pointer when handling DBus smartcard parameters

Browse source 
Smartcard parameter update via DBus ended up re-initializing the EAPOL
state machine without updating the pointer inside WPA state machine.
This can trigger a segfault when EAP layer attempts to use the old
reference. Fix this by re-initializing the pointer inside WPA state
machine.
