conf: virDomainMemoryDefValidate: Improve error message

An explicit limit would be more user friendly. Add the limit to error message.

Before this commit:
```
error: requested size must be smaller than or equal to @size
```

Now:
```
error: requested size must be smaller than or equal to @size (8388608KiB)
```
