mtd: onenand: fix deadlock in onenand_block_markbad

[ Upstream commit 5e64c29e ]

Commit 5942ddbc ("mtd: introduce mtd_block_markbad interface")
incorrectly changed onenand_block_markbad() to call mtd_block_markbad
instead of onenand_chip's block_markbad function. As a result the function
will now recurse and deadlock. Fix by reverting the change.
