    Fix: libcrmcommon: filter attributes with '#' from XML fields
    
    The PE passes node attributes to fence agents using hash2metafield(),
    but this would generate invalid XML syntax with per-operation fail counts,
    which contain '#'. Cluster-generated attributes aren't intended to be passed
    anyway, so just filter such names out when adding to XML.
