mtd: rawnand: oxnas: Fix the probe error path 



commit 154298e2a3f6c9ce1d76cdb48d89fd5b107ea1a3 upstream.

nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.

While at it, be consistent and move the function call in the error
path thanks to a goto statement.
