[PATCH 7/9] hw/ide/ahci: trigger either error IRQ or regular IRQ, not both

From: Niklas Cassel According to AHCI 1.3.1, 5.3.8.1 RegFIS: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.
