UBIFS: amend ubifs_recover_leb interface
Instead of passing "grouped" parameter to 'ubifs_recover_leb()' which tells whether the nodes are grouped in the LEB to recover, pass the journal head number and let 'ubifs_recover_leb()' look at the journal head's 'grouped' flag. This patch is a preparation to a further fix where we'll need to know the journal head number for other purposes. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
