KVM: add missing compat KVM_CLEAR_DIRTY_LOG
commit 8750f9bbda115f3f79bfe43be85551ee5e12b6ff 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.
