AHCI - Bug fixes - primary port probe and TFD flushing.

* The primary port probe was skipping the software reset step.

* ahci_flush_tfd() was looping on the SERR.DIAG.X bit with a 10ms delay,
  but on some parts this bit gets re-set very quickly if the port is
  in a COMRESET state.  Remove the loop, just use an if() instead.
