Ensure the file system hasn't been shut down before waiting for a free
zone to become available, because that won't happen on a shut down
file system. Without this processes can occasionally get stuck in
the allocator wait loop when racing with a file system shutdown.
This sporadically happens when running generic/388 or generic/475.
