[SPARK-18953][CORE][WEB UI] Do now show the link to a dead worker on the master page
## What changes were proposed in this pull request?
For a dead worker, we will not be able to see its worker page anyway. This PR removes the links to dead workers from the master page.
## How was this patch tested?
Since this is UI change, please do the following steps manually.
**1. Start a master and a slave**
```
sbin/start-master.sh
sbin/start-slave.sh spark://10.22.16.140:7077
```

**2. Stop the slave**
```
sbin/stop-slave.sh
```
