From: Niklas Cassel <niklas.cassel@wdc.com>
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.
NOTE: for QEMU platforms that use SeaBIOS, this patch depends on QEMU
commit 784155cdcb02 ("seabios: update submodule to git snapshot"), and
QEMU commit 14f5a7bae4cb ("seabios: update binaries to git snapshot").
