[kms-test] [PATCH 9/7] kmstest: Raise clear exception when property is not found

[Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>]

When converting a property value string to an integer, if the property
is not found, an AttributeError exception is raised and reports that
"'NoneType' object has no attribute 'type'". This isn't very clear,
replace it with a RuntimeError with a proper message.
