kernel - Fix CAM tag reservation for AHCI and SILI driver

* These drivers were adjusting the number of available tags upward
  using the wrong CAM call, which resulted in CAM not actually queueing
  multiple tags.  Use the correct call.

* With the issue fix and verified up to a combined 31 read and write
  requests can now be queued in parallel to a SATA drive via the AHCI
  driver.  It does appear to make a difference.
