displayio: Fix "bus type" problem introduced at 8cba145c9029
When allocate_display_bus_or_raise was factored out, the assignment
of the bus's Python type was lost. Restore it.
This would have affected displays of any type other than RGBMatrix, when
they were created dynamically. Boards with displays configured in flash
were unaffected.
Closes: #2792
