UBI: use raw mtd read function in debugging code
This change affects only the debugging code. Namely, use mtd->read() function instead of ubi_io_read() to avoid bit-flips injection (ubi_dbg_is_bitflip()) which we do not want on the debugging path. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
