MST Hub Disconnect/Suspend results in crash since 5.16.0-rc8

Happens on Lenovo Thinkpad T14 with Lenovo 40AS MST Hub Dock. Can be reproduced with unplugging the dock without shutdown of the Machine and waiting till it tries to enter Standby. Not sure if the disconnect or the Standby is the issue.

AMD Ryzen 7 PRO 4750U Archlinux
