AHCI: Do not (re)map FB/CLB buffers while not running
The FIS Receive Buffer and Command List Buffer pointers should not be edited while the FIS receive engine or Command Receive engines are running. Currently, we attempt to re-map the buffers every time they are adjusted, but while the AHCI engines are off, these registers may contain stale values, so we should not attempt to re-map these values until the engines are reactivated.
