José Expósito ed15511a77 drm/vkms: Fix use after free and double free on init error

If the driver initialization fails, the vkms_exit() function might
access an uninitialized or freed default_config pointer and it might
double free it.

Fix both possible errors by initializing default_config only when the
driver initialization succeeded.
