[MTD] Correct partition failed erase address
If an erase operation fails, the address at which the failure occurred is returned by the driver. The MTD partition must adjust this address (by subtracting the partition offset) before returning to the caller. This was not happening, which caused JFFS2 to mark the wrong block bad!
