    [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!
