mtd: rawnand: rockchip: Fix the return value in case of ECC fail

Browse Source 
The former ECC fail return value -1 is not the correct one, change
to return 0 and let the nand base handle it. The mistake value
causing file system to be unable to detect the ECC fail status and
unable to make corresponding optimization processing.
