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 ........

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