Wentao Liang bfbbef7f1d mtd: rawnand: Add status chack in r852_ready() 
commit b79fe18299 upstream.

In r852_ready(), the dev get from r852_get_dev() need to be checked.
An unstable device should not be ready. A proper implementation can
be found in r852_read_byte(). Add a status check and return 0 when it is
unstable.

Fixes: 50a487e771 ("mtd: rawnand: Pass a nand_chip object to chip->dev_ready()")
