    FBSD: close race in afs_root
    Previously, we called afs_PutVCache(afs_globalVp) directly.  This
    is unsafe because PutVCache acquires locks which can sleep, losing
    the serialization of the GLOCK.  In rare circumstances, this can
    result in two threads simultaneously making that call, and the
    second one would panic in vputx() with a negative refcount.
    Close the race by using a local variable for the afs_PutVCache()
    calls, applying the change to afs_globalVp before dropping the GLOCK.
    While here, fix up other race conditions.
