When eap::config_method_eaphost::get_method_id() returns EAP-MSCHAPv2, XML-to-BLOB gets confused and picks native EAP-MSCHAPv2 implementation. Therefore, it was updated to always return unknown EAP type. Outer method does not need to know the exact method implemented by EapHost inner method. Signed-off-by: Simon Rozman <simon@rozman.si>
