Zhang Wei 1083d494cd Forbid exec a restarting container ...

Currently if we exec a restarting container, client will fail silently,
and daemon will print error that container can't be found which is not a
very meaningful prompt to user.

This commit will stop user from exec a restarting container and gives
more explicit error message.
