I mentioned this once already but: really, I am genuinely impressed at this! I
never expected to see this monitor ever work. Also, thank you a ton for adding
the payload table verification stuff here. For the whole series:

The DELL P2715Q monitor's MST hub has a payload allocation problem,
where the VCPI used to reserve the last two time slots (at position
0x3e, 0x3f) in the hub's payload table, this VCPI can't be reused for
later payload configurations.
The problem results at least in streams reusing older VCPIs
