efi_selftests: add extra testcases on controller handling
We recently fixed a few issues wrt to controller handling. Add a few
test cases to cover the new code.
- return EFI_DEVICE_ERROR the first time the protocol interface of
the controller is uninstalled, after all the children have been
disconnected. This should make the drivers reconnect
- add tests to verify controllers are reconnected when uninstalling a
protocol fails
- add tests to make sure EFI_NOT_FOUND is returned if a non existent
interface is being removed
