H Hartley Sweeten d4702669b0 mtd: fix memory leak in mtd_dataflash
Fix a potential memory leak in mtd_dataflash driver.

The private data that is allocated when registering a DataFlash
device with the MTD subsystem is not released if an error occurs
when add_mtd_partitions() or add_mtd_device() is called.  Fix this
by adding an error path.  The memory is already released during a
remove.

Also, add a dev_set_drvdata(&spi->dev, NULL) before the kfree() so
that the spi device does not reference invalid data.
