drm/qxl: fix use of uninitialized variable In function qxl_release_alloc(), when kmalloc() returns a NULL pointer, it returns value 0 and parameter *ret is uninitialized. 0 means no error to the callers of qxl_release_alloc(). The callers keep going and will try to reference the uninitialized variable. This patch fixes the bug, returning "-ENOMEM" when kmalloc() fails.
