             Summary: Quota by storage type usage incorrectly initialized upon namenode restart

This was found by [~kihwal] as part of HDFS-8865 work in this [comment|https://issues.apache.org/jira/browse/HDFS-8865?focusedCommentId=14660904&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14660904].

The unit test testQuotaByStorageTypePersistenceInFsImage/testQuotaByStorageTypePersistenceInFsEdit failed to detect this because they were using an obsolete
FsDirectory instance. Once added the highlighted line below, the issue can be reproed.

{code}
++++>fsdir = cluster.getNamesystem().getFSDirectory();
INode testDirNodeAfterNNRestart = fsdir.getINode4Write(testDir.toString());
{code}
