Merge pull request #13910 from x3lif:Issue_13908

* Fix Issue 13908

Allocate the matrix _Jo only when the solver needs it (ie when solver.state == CvLevMarq::CALC_J)

* Fix calib3D unit test

Fix _Jo allocation when stddev is not empty

* Removing trailing whitespaces

* scope _dp* variables

* fix whitespaces
