cxl/core: Fix incorrect vendor debug UUID define
When user send a mbox command whose opcode is CXL_MBOX_OP_CLEAR_LOG and the in_payload is normal vendor debug log UUID according to the CXL specification cxl_payload_from_user_allowed() will return false unexpectedly, Sending mbox cmd operation fails and the kernel log will print: Clear Log: input payload not allowed. All CXL devices that support a debug log shall support the Vendor Debug Log to allow the log to be accessed through a common host driver, for any device, all versions of the CXL specification define the same value with Log Identifier of: 5e1819d9-11a9-400c-811f-d60719403d86 Refer to CXL spec r3.1 Table 8-71 Fix the definition value of DEFINE_CXL_VENDOR_DEBUG_UUID to match the CXL specification.
