kernel - Make sys_ioctl() MPSAFE

* Tokenize the ioctl mapper and stay MPSAFE through the fo_ioctl() call.
  Beyond that it will be determined by the fops driver and for vnodes
  will be determined by the MNTK_*_MPSAFE flags.

* HAMMER's ioctls will now be entered without holding the MP lock, aka
  reblock, prune.
