[PATCH 084/104] Virtiofsd: fix memory leak on fuse queueinfo

[Dr. David Alan Gilbert (git)]

From: Liu Bo <bo....@linux.alibaba.com>

For fuse's queueinfo, both queueinfo array and queueinfos are allocated in
fv_queue_set_started() but not cleaned up when the daemon process quits.

This fixes the leak in proper places.
