  • OpenCL kernel cleanup processing is asynchronous and can be called even after forced clFinish()
  • buffers are released later in asynchronous mode
  • silence these false positive cases for asynchronous cleanup

relates #5317

resolves #10651
resolves #18034

Message example:

! OPENCV warning: getUMat()/getMat() call chain possible problem.
!                 Base object is dead, while nested/derived object is still alive or processed.
!                 Please check lifetime of UMat/Mat objects!
