2.3.13 - fails to unlinking quota file

[Wolfgang Powisch]

I think I've encountered a bug in 2.3.13, when I delete a Mailbox, the
corresponding quota-file isn't removed, and log-output shows that it
tries to unlink a wrong filename. All other files are removed correctly.

I'm using default quota_db (quotalegacy) and fulldirhash.

Adding some more debug output to code it seems that quota->root get's
free'd at some point before the commit is called, which should unlink 
the file.
