When the query decoding fails at the beginning of WaitContainerLibpod(), the Error() sets the header but doesn't returns after that.

This causes the execution flow to reach the WriteResponse() at the end of WaitContainerLibpod(), which attempts to set another header, thus causing the following error:

http: superfluous response.WriteHeader call from github.com/containers/podman/pkg/api/handlers/utils.WriteResponse (handler.go:124)
