mtd: nand: fully initialize mtd_oob_ops
We're not initializing the ooblen field. Our users don't care, since they check that oobbuf == NULL first, but it's good practice to zero unused fields out. We can drop the NULL initializations since we're memset()ing the whole thing. Noticed by Coverity, CID #200821, #200822 Signed-off-by: Brian Norris <computersforpeace@gmail.com>
