    xen: remove unused function ERR_CAST
    
    Function ERR_CAST contains a violation of MISRA C:2012 Rule 11.8,
    whose headline states:
    "A conversion shall not remove any const, volatile or _Atomic qualification
    from the type pointed to by a pointer".
    
    Since the function has no users, it is appropriate to remove it.
