Andrew Goodbody a5c83da3cc mtd: nand: Prevent dereference of NULL pointer ...

In nand_wait_ready there is a loop that includes a NULL check for
chip->dev_ready before it is dereferenced. Use a NULL check once the
loop is exited as well to cover the case where it exits due to a timeout
and it is therefore not known if chip->dev_ready is NULL or not.

This issue found by Smatch.
