Bug #10901

After review fix
Copy from internal state to share state only when in lock write
mode (happens only when lock table x write has been performed since
update_state_info is only called when holding a TL_READ_NO_INSERT
lock normally. Previous patch would have failed in combination with
delayed writes.
