drm/xe/svm: Fix regression disallowing 64K SVM migration
commit d6fb4f01736a1d18cc981eb04fa2907a7121fc27 upstream.
When changing the condition from >= SZ_64K, it was changed to <= SZ_64K.
This disallows migration of 64K, which is the exact minimum allowed.
Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/5057
