Emanuele Giuseppe Esposito 87e4d4a205 pylint: fix errors and warnings generated by tests/qemu-iotests/297
Test 297 in tests/qemu-iotests currently fails: pylint has
learned new things to check, or we simply missed them.

All fixes in this patch are related to additional spaces used
or wrong indentation. No functional change intended.
