I noticed that the AHCI CI (cmd issue) reg wasn't getting cleared after error ints resulting in no further commands being successfully issued to the port. This patch fixes. All that's really needed is the 1's complement but I also removed the disabling/enabling of the FIS_RX b/c this isn't spec'd as necessary when handling error ints.
