Fix: correct issue pointed out by static analysis (#3044)

### Description
Static analysis complained that although a destructor had been defined in class vfio_device, there was not a corresponding copy ctor nor assignment operator. The variable is treated as a Singleton in the application, so no copying occurs.  Implementing the constructor and assignment operator as deleted solves the issue.

### Collateral (docs, reports, design examples, case IDs):
