Without this patch it was possible for a different thread that calls nfs_asyncio() to snitch a newly created nfsiod thread that was intended for another caller of nfs_asyncio(), because the nfs_iod_mtx mutex was unlocked while the new nfsiod thread was created. This patch labels the newly created nfsiod, so that it is not taken by another caller of nfs_asyncio(). This is believed to fix the problem reported on the freebsd-stable email list under the subject: FreeBSD NFS client/Linux NFS server issue.
