Subject: [PATCH] deleted the unused random_device variables because they
 caused a warning that was treated like an error. (#18543)

deleted the unused random_device variables because they caused a warning
that was treated like an error.

**_Please check if the declaration is required for the random number
generation. if so, there need to be a dummy reference to the variable or
turning off the warning as error behavior._**
