[PATCH] NAND: Free asprintf()-allocated space upon mtd device deletion.

[Robert P. J. Day]

Given that add_mtd_device() invokes asprintf() thusly:

  mtd->cdev.name = asprintf("nand%d", mtd->class_dev.id);
  ...
  mtd->param_size.value = asprintf("%u", mtd->size);
  ...
  mtd->cdev_oob.name = asprintf("nand_oob%d", mtd->class_dev.id);

make sure del_mtd_device() frees that in the reverse order.
