drm/dp/mst: Always clear proposed vcpi table for port.

Browse source

commit fd2d2bac6e upstream.

Not clearing mst manager's proposed vcpis table for destroyed connectors when the manager is stopped leaves it pointing to unrefernced memory, this causes pagefault when the manager is restarted when plugging back a branch.
