UBIFS: switch to ubifs_leb_read
Instead of using 'ubi_read()' function directly, used the 'ubifs_leb_read()' helper function instead. This allows to get rid of several redundant error messages and make sure that we always have a stack dump on read errors. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
