ovl: honor flag MS_SILENT at mount This patch hides error about missing lowerdir if MS_SILENT is set. We use mount(NULL, "/", "overlay", MS_SILENT, NULL) for testing support of overlayfs: syscall returns -ENODEV if it's not supported. Otherwise kernel automatically loads module and returns -EINVAL because lowerdir is missing.
