UBIFS: double check that buds are replied in order
Commit 52c6e6f990669deac3f370f1603815adb55a1dbd provides misleading infomation in the commit messages - buds are replied in order. And the real reason why that fix helped is probably because it made sure we seek head even in read-only mode (so deferred recovery will have seeked heads). This patch adds an assertion which will fire if we reply buds out of order. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
