drm/nouveau/svm: check for SVM initialized before migrating

[ Upstream commit 822cab6150d3002952407a8297ff5a0d32bb7b54 ]

When migrating system memory to GPU memory, check that SVM has been
enabled. Even though most errors can be ignored since migration is
a performance optimization, return an error because this is a violation
of the API.
