Users have come to expect that the space accounting information in
statfs and getquota reports are fairly accurate.  Now that we inactivate
inodes from a background queue, these numbers can be thrown off by
whatever resources are singly-owned by the inodes in the queue.  Flush
the pending inactivations when userspace asks for a space usage report.

Makes sense. These aren't perf/latency sensitive operations, so
waiting on completion of a flush shouldn't be a big deal.
