Subject: watchdog: core: Fix devres_alloc() allocation size

From: Guenter Roeck <linux@roeck-us.net>

commit 2e91838bf7ffdedabdb29e091207d6531d04ef4f upstream.

Coverity reports:

Passing argument 152UL /* sizeof (*wdd) */ to function __devres_alloc_node
and then casting the return value to struct watchdog_device ** is
suspicious.

Allocation size needs to be sizeof(*rcwdd), not sizeof(*wdd).
