It looks like eap_server_get_name() is used only in debug and log
messages and it should be fine to change its behavior for the
unrecognized EAP type case. I don't think "(nil)" is a very good string
to use here since it results in number of debug messages with "((nil))".
I'll replace this with "unknown" which is at least more readable if
nothing else. In addition, eap_server_get_name() function documentation
needs to be updated (did that as well) to avoid leaving it claiming to
return NULL if EAP method was not found.
