UBIFS: synchronize write-buffer before switching to the next bud
Currently when UBIFS fills up the current bud (which is the last in the journal head) and switches to the next bud, it first writes the log reference node for the next bud and only after this synchronizes the write-buffer of the previous bud. This is not a big deal, but an unclean power cut may lead to a situation when we have corruption in a next-to-last bud, although it is much more logical that we have to have corruption only in the last bud. This patch also removes write-buffer synchronization from 'ubifs_wbuf_seek_nolock()' because this is not needed anymore (we synchronize the write-buffer explicitly everywhere now) and also because this is just prone to various errors.
