UBI: gluebi: rename misleading variables
Both names 'total_read' and 'total_written' are actually used as the number of bytes left to read and write. Fix this confusion by renaming both to 'bytes_left'. Signed-off-by: Ezequiel Garcia <elezegarcia@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
