Re: [U-Boot] [PATCH] test/py: Fix exception, do not parametrize with empty set

If the parameter set is empty, the pytest setup fails:

This aborts pytest_runtest_makereport and later leads to an exception during the report generation, as the call to log.start_section(...) is never executed:

Exception: Block nesting mismatch:
"test_dfu[env__usb_dev_port0-env__dfu_config0]" ""

This patch causes failures with pytest 2.5 when env__dfu_configs is an empty list or not set at all. I've created an alternative patch that seems to work with both pytest 2.5 and 3, which I'll send in a minute.
