RE: [PATCH] cxl/mbox: Fix missing variable payload checks in cmd size validation

The conversion of command sizes to unsigned missed a couple of checks against variable size payloads during command validation, which made all variable payload commands unconditionally fail. Add the checks back using the new CXL_VARIABLE_PAYLOAD scheme.

Ah, looks good. Need to get label read/write regression test into cxl-cli post-haste.
