    gccrs: Remove unused error constructor and getter
    
    These constructor for eroneous state are not in use anymore since we
    replaced this error state with an optional in the parent nodes.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-expr.h: Remove error getter and constructor.
