drm/xe/svm: Fix regression disallowing 64K SVM migration

Browse Source 
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
Fixes: 794f5493f5 ("drm/xe: Strict migration policy for atomic SVM faults")
