UBIFS: do not allocate unneeded scan buffer
In 'ubifs_replay_journal()' we allocate 'sbuf' for scanning the log. However, we already have 'c->sbuf' for these purposes, so do not allocate yet another one. This reduces UBIFS memory consumption while recovering. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
