Subject: [PATCH] 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.

Subject: [PATCH] e2fsck: update quota when deallocating a bad inode
If a bad inode is found it will be deallocated. However, if the filesystem has
quota enabled, the quota information isn't being updated accordingly. This
issue was detected by running fstest ext4/019.
This patch fixes the issue by decreasing the inode count from the
quota and, if blocks are also being released, also subtract them as well.
While there, and as suggested by Andreas Dilger, the deallocate_inode()
function documentation is also updated by this patch to make it clear what
that function really does.
