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.
