mtd: docg4: ecc.read_page() returns 0 on uncorrectable errors
Currently the docg4's ecc.read_page() method returns -EBADMSG when
uncorrectable bitflips occur. This is wrong; 0 should be returned in
this case. An error code should only be returned by this method in the
case of a hardware error (probably -EIO).
