UBIFS: introduce a "grouped" journal head flag
Journal heads are different in a way how UBIFS writes nodes there. All normal
journal heads receive grouped nodes, while the GC journal heads receives
ungrouped nodes. This patch adds a 'grouped' flag to 'struct ubifs_jhead' which
describes this property.
This patch is a preparation to a further recovery fix.
