Paolo Bonzini 52acb6c147 KVM: add missing compat KVM_CLEAR_DIRTY_LOG ...

commit 8750f9bbda upstream.

The arguments to the KVM_CLEAR_DIRTY_LOG ioctl include a pointer,
therefore it needs a compat ioctl implementation.  Otherwise,
32-bit userspace fails to invoke it on 64-bit kernels; for x86
it might work fine by chance if the padding is zero, but not
on big-endian architectures.
