Short description of error
Error getting Cycles GPU devices if device_type is set to NONE (and thus related part of the UI will disappear)

Exact steps for others to reproduce the error
From the default startup file:

set User Preferences > System > Cycles Render Devices to "None"
switch the Render Engine to "Cycles"
switch the Device to "GPU Compute"
following error will occur in the console (and thus related part of the UI will disappear)

Traceback (most recent call last):
  File "/build_linux/bin/2.91/scripts/modules/bpy_types.py", line 808, in draw_ls
    func(self, context)
