Added EEH test cases for PCI PT NIC devices

[TasmiyaNalatwad]

Added 2 test cases

1. Inject EEH from host console for pci pt device
2. Inject EEH from guest console for pci pt device

[TasmiyaNalatwad]

Currently eeh from host is supported and it gets into permanent failure after 2 eeh injections, so tested code with the 2 injections , and eeh inside guest is still feature under development, hence it is failing here.
