Stefan Hajnoczi cdc497c692 virtiofsd: prevent FUSE_INIT/FUSE_DESTROY races
When running with multiple threads it can be tricky to handle
FUSE_INIT/FUSE_DESTROY in parallel with other request types or in
parallel with themselves.  Serialize FUSE_INIT and FUSE_DESTROY so that
malicious clients cannot trigger race conditions.
