Subject[PATCH] kernel/watchdog: fix warning -Wunused-variable for watchdog_allowed_mask in ppc64
Date
In ppc64 config if `CONFIG_SOFTLOCKUP_DETECTOR` is not set then it
warns for unused declaration of `watchdog_allowed_mask` while building,
move the declaration inside ifdef later in the code.

```
kernel/watchdog.c:47:23: warning: ‘watchdog_allowed_mask’ defined but not used [-Wunused-variable]
static struct cpumask watchdog_allowed_mask __read_mostly;
```
