[PATCH] hw/ide: Remove status register read side effect

[jasper.lowell]

The Linux libATA API documentation mentions that on some hardware,
reading the status register has the side effect of clearing the
interrupt condition. When emulating the generic Sun4u machine running
Solaris 10, the Solaris 10 CMD646 driver exits fatally because of this
emulated side effect. This side effect is likely to not exist on real
CMD646 hardware.
