Since moving the message buffers off the stack, the dynamically allocated get-prop-descriptor request buffer is incorrectly sized due to using the pointer rather than request-struct size when creating the operation.
Fortunately, the pointer size is always larger than this one-byte request, but this could still cause trouble on the remote end due to the unexpected message size.
