  Log:
  Lock the AMR driver:
  - Introduce the amr_io_lock to control access to command queues, bio queues,
    and the hardware.
  - Eliminate the taskqueue and do all completion processing in the ithread.
  - Assign a static slot number to each command instead of doing a linear
    search for free slots each time a command is needed.
  - Modify the interrupt handler to more closely match what Linux does, for
    safety.
