drm/vkms: Fix missing kmalloc allocation failure check
Currently the kmalloc allocation for config is not being null
checked and could potentially lead to a null pointer dereference.
Fix this by adding the missing null check.
Addresses-Coverity: ("Dereference null return value")
Fixes: 2df7af93fdad ("drm/vkms: Add vkms_config type")
