KVM: Fix KVM_GET_MSR_INDEX_LIST
commit e125e7b6944898831b56739a5448e705578bf7e2 upstream.
So far, KVM copied the emulated_msrs (only MSR_IA32_MISC_ENABLE) to a
wrong address in user space due to broken pointer arithmetic. This
caused subtle corruption up there (missing MSR_IA32_MISC_ENABLE had
probably no practical relevance). Moreover, the size check for the
user-provided kvm_msr_list forgot about emulated MSRs.
