KVM: x86: Copy filter arg outside kvm_vm_ioctl_set_msr_filter()

Browse source

In the next patch we want to introduce a second caller to
set_msr_filter() which constructs its own filter list on the stack.
Refactor the original function so it takes it as argument instead of
reading it through copy_from_user().
