From: Paolo Bonzini <[email protected]> superio_ioport_readb can read the 256th element of the array. Coverity reports an out-of-bounds write in superio_ioport_writeb, but it does not show the corresponding out-of-bounds read because it cannot prove that it can happen. Fix the root cause of the problem (zhanghailang's patch instead fixes the logic in superio_ioport_writeb).
