UBIFS: add a print, fix comments and more minor stuff
This commit adds a reserved pool size print and tweaks the prints to make them look nicer. It also fixes and cleans-up some comments. Additionally, it deletes some blank lines to make the code look a little nicer. In other words, nothing essential. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
