Since Linux 4.6, mtd->priv no longer points to the NAND specific structure. Under 4.9 it contains NULL, thus using it to access the fields of the nand_chip structure causes an invalid pointer dereference. Update the code to use the mtd_to_nand() helper under 4.9 to obtain the address of the chip specific data. Compile tested only.
