When there is an error, we need to raise a TFES error irq, see AHCI 1.3.1, 5.3.13.1 SDB:Entry. If ERR_STAT is set, we jump to state ERR:FatalTaskfile, which will raise a TFES IRQ unconditionally, regardless if the I bit is set in the FIS or not. Thus, we should never raise a normal IRQ after having sent an error IRQ. It is valid to signal successfully completed commands as finished in the same SDB FIS that generates the error IRQ. The important thing is that commands that did not complete successfully (e.g. commands that were aborted, do not get the finished bit set). Before this commit, there was never a TFES IRQ raised on NCQ error.
