When no --wq-option flag is passed to dpdk_idxd_cfg.py script, the
default value used by argparse is None. This leads to later errors which
are expecting an array value:
TypeError: 'NoneType' object is not iterable
This is fixed by specifying that the empty array should be the default
if no flags are passed.
