[PATCH] drm/dp-mst: remove unused variable

[Anders Roxell]

The variable 'dev' is no longer used and the compiler rightly complains
that it should be removed.

../drivers/gpu/drm/drm_dp_mst_topology.c: In function ‘drm_atomic_get_mst_topology_state’:
../drivers/gpu/drm/drm_dp_mst_topology.c:4187:21: warning: unused variable ‘dev’ [-Wunused-variable]
  struct drm_device *dev = mgr->dev;
                     ^~~

Rework to remove the unused variable.

Fixes: 83fa9842afe7 ("drm/dp-mst: Drop connection_mutex check")
