KVM: set no_llseek in stat_fops_per_vm
In vm_stat_get_per_vm_fops and vcpu_stat_get_per_vm_fops, since we use nonseekable_open() to open, we should use no_llseek() to seek, not generic_file_llseek(). Signed-off-by: Geliang Tang <geliangtang@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
