Jeff Epler b1592564b2 displayio: Fix matrixportal crash 
An RGBMatrix has no bus and no bus_free method.  It is always possible
to refresh the display.

This was not a problem before, but the fix I suggested (#3449) added
a call to core_bus_free when a FramebufferDisplay was being refreshed.
This was not caught during testing.

This is a band-aid fix and it brings to light a second problem in which
a SharpDisplay + FrameBuffer will not have a 'bus' object, and yet does
operate using a shared SPI bus.  This kind of display will need a
"bus-free" like function to be added, or it can have problems like
#3309.
