mtd: onenand: fix deadlock in onenand_block_markbad

[ Upstream commit 5e64c29e98bfbba1b527b0a164f9493f3db9e8cb ]

Commit 5942ddbc500d ("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.
