kernel - CAM mpsafe issues

* Lock the CAM bus when making asynchronous xpt callbacks.  This code
  previously depended on the MP lock but failed to use the correct
  sim lock, and AHCI/SILI now use their own locks.

* Remove a few other unnecessary mplocks.

* Redo the bus counting code to be MPSAFE.
