[FGL] Solutions for QuotaUpdated when completed block

The block size will not be changed after committed, so it's the time to update quota.

HDFS-10843 moves quota update logic when completing block to fix some bugs. BR and IBR may complete block, so it means that the BR and IBR needs to update quota for the full directory tree.

This modification couples file operations and block operations, it results the BR and IRB needs to hold the global FS lock. So it is unreasonable.

I think HDFS-17481 can also fix the bugs mentioned in HDFS-10843.
