virtio-pci: thinko fix
Since patch ed757e140c0ada220f213036e4497315d24ca8bct, virtio will
sometimes clear all status registers on bus master disable, which loses
information such as VIRTIO_CONFIG_S_FAILED bit. This is a result of
a patch being misapplied: code uses ! instead of ~ for bit
operations as in Yan's original patch. This obviously does not make
sense.
