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.
