[PATCH] mtd: onenand: fix parameter list build warning

[Randy Dunlap <rdunlap@infradead.org>]

From: Randy Dunlap <rdunlap@infradead.org>

Fix build warning in <linux/mtd/onenand.h> by adding a "stub" struct
for mtd_oob_ops:

include/linux/mtd/onenand.h: warning: 'struct mtd_oob_ops' declared inside parameter list [enabled by default]
include/linux/mtd/onenand.h: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]

Fixes: 607d1cb10426 ("[MTD] [OneNAND] proper onenand_bbt_read_oob() prototype")
