UBIFS: change bud replay function conventions
This is a minor preparation patch which changes 'replay_bud()' interface - instead of passing bud lnum, offs, jhead, etc directly, pass a pointer to the bud entry which contains all the information. The bud entry will be also needed in one of the following patches. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
