watchdog: rc32434_wdt: fix ioctl error handling
commit 10e7ac22cdd4d211cef99afcb9371b70cb175be6 upstream.
Calling return copy_to_user(...) in an ioctl will not do the right thing
if there's a pagefault: copy_to_user returns the number of bytes not
copied in this case.
Fix up watchdog/rc32434_wdt to do
return copy_to_user(...)) ? -EFAULT : 0;
instead.
