KVM: x86: Add compat handler for KVM_X86_SET_MSR_FILTER
The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in struct which means it has a different struct size depending on whether it gets called from 32bit or 64bit code. This patch introduces compat code that converts from the 32bit struct to its 64bit counterpart which then gets used going forward internally. With this applied, 32bit QEMU can successfully set MSR bitmaps when running on 64bit kernels.
