> When we started routers with *dfs.federation.router.quota.enable=false*, and 
> try to setQuota through them, NullPointerException caught.
> The cuase of NPE is that the Router#quotaManager not initialized when 
> dfs.federation.router.quota.enable=false,
>  but when executing setQuota rpc request inside router, we wolud use it in 
> method Quota#isMountEntry without null check .
> I think it's better to check whether Router#isQuotaEnabled is true before use 
> Router#quotaManager, and throw an IOException with readable message if need.
