drm/xe/svm: fix dereferencing error pointer in drm_gpusvm_range_alloc()
xe_svm_range_alloc() returns ERR_PTR(-ENOMEM) on failure and there is a
dereference of "range" after that:
--> range->gpusvm = gpusvm;
In xe_svm_range_alloc(), when memory allocation fails return NULL
instead to handle this situation.
