[PATCH] cxl/mbox: Add the CXL 4.0 command return codes 001Fh and 0020h

[Gaobin Huang]

CMD_CMD_RC_TABLE ends at 001Eh (Invalid Extent List), but the command
return code table in CXL r4.0 Table 8-208 also defines:

  001Fh  Transfer Out of Order: The input parameters data transfer was
         aborted because it occurred out of order.
  0020h  Request Abort Not Supported by Background Operation: The ongoing
         background operation does not support the Request Abort command.

A device that reports either code is described as an unknown return code.
Add both entries, mapped to -ENXIO.
