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.

The CI Python 3.6 and 3.7 are failing as it is not understanding some of the spellings like My name added as Author and "EEH"
Could someone help me in fixing these spelling errors .

Thank You
