Pablo Martin-Gomez 6463cbe08b mtd: spinand: fix memory leak of ECC engine conf 
Memory allocated for the ECC engine conf is not released during spinand
cleanup. Below kmemleak trace is seen for this memory leak:

unreferenced object 0xffffff80064f00e0 (size 8):
  comm "swapper/0", pid 1, jiffies 4294937458
  hex dump (first 8 bytes):
    00 00 00 00 00 00 00 00                          ........
  backtrace (crc 0):

    __device_attach+0x188/0x24c
    device_initial_probe+0x10/0x20
    bus_probe_device+0x11c/0x160

Fix the leak by calling nanddev_ecc_engine_cleanup() inside
spinand_cleanup().
