ahci: prohibit "restarting" the FIS or CLB engines
If the FIS or DMA engines are already started, do not allow them to be
"restarted." As a side-effect of this change, the migration post-load
routine must be modified to cope. If the engines are listed as "on"
in the migrated registers, they must be cleared to allow the startup
routine to see the transition from "off" to "on".
As a second side-effect, the extra argument to ahci_cond_engine_start
is removed in favor of consistent behavior.
