[PATCH] MTD: make s3c2410's correct_data indicate an error for multi-bit read errors

From: Matt Reimer <mreimer@vpop.net>

If there were multiple bit errors in the data s3c2410_nand_correct_data()
was returning 0 (no error) instead of -1, so the upper layers (like JFFS2)
would not know the data is corrupt.
