// RELOCATE_ONE - Relocate a single pointer in a client buffer.
//
// Note: this macro is dependent on parameter names as indicated in the
//       description below.  On error, this macro goes to 'Cleanup' with
//       'Status' set to the NT Status code.
//
// The MaximumLength is forced to be Length.
//
// Define a macro to relocate a pointer in the buffer the client passed in
// to be relative to 'ProtocolSubmitBuffer' rather than being relative to
// 'ClientBufferBase'.  The result is checked to ensure the pointer and
// the data pointed to is within the first 'SubmitBufferSize' of the
// 'ProtocolSubmitBuffer'.
//
// The relocated field must be aligned to a WCHAR boundary.
//
//  _q - Address of UNICODE_STRING structure which points to data to be
//       relocated
