drm/dp/mst: Remove port after removing connector.

Browse Source 
The port is removed synchronously, but the connector delayed.
This causes a use after free which can cause a kernel BUG with
slug_debug=FPZU. This is fixed by freeing the port after the
connector.

This fixes a regression introduced with
6b8eeca65b
"drm/dp/mst: close deadlock in connector destruction."
