drm/xe/svm: Avoid duplicate eviction on get_pages() failure

xe_svm_range_get_pages() already calls drm_gpusvm_range_evict()
internally when it fails with -EOPNOTSUPP. Remove the eviction
call in the caller to prevent duplicate handling.

Fixes: e0ff0d7cf928 ("drm/xe/svm: Refactor usage of drm_gpusvm* function in xe_svm")
