Subject: drm/vkms: Fix connector leak at the module removal
Git-commit: 2ead1be54b22ccdc93d3030172993e363128f1b4
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Currently, vkms shows an error message if the following steps occur: (1)
load vkms, (2) perform any specific operation in the vkms (e.g., run an
IGT test), and (3) unload the module. The following error message
emerges:

[drm:drm_mode_config_cleanup [drm]] *ERROR* connector Virtual-1 leaked!

This commit fixes this error by calling drm_atomic_helper_shutdown()
before drm_mode_config_cleanup, which turns off the whole display
pipeline and remove a reference related to any connector.
