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.
