[PATCH 6/9] hw/intc/s390x: Fix payload to KVM_HAS_DEVICE_ATTR ioctl

[Eric Farman <farman@linux.ibm.com>]

The ioctl to determine whether KVM_DEV_FLIC_CLEAR_IO_IRQ is present
receives the contents of the attribute struct as its payload,
rather than a pointer to the payload itself as is convention.

This may result in erroneous errors from the ioctl, which would
result in clear_io_supported being false when it otherwise could
be used (which is helpful in device recovery).
