e2fsck: update quota accounting after directory optimization

e2fsck: update quota accounting after directory optimization

In "Pass 3A: Optimizing directories", a directory may have it's size reduced.
If that happens and quota is enabled in the filesystem, the quota information
will be incorrect because it doesn't take the rehash into account.  This issue
was detected by running fstest ext4/014.

This patch simply updates the quota data accordingly, after the directory is
written and it's size has been updated.
