net/ixgbe: fix probe with no devargs

Initialise rte_ethdev_args parameters to zero to handle
the case where no devargs are passed to the IXGBE PF on
device probe, so that there is no invalid attempts to create
representor ports.

Coverity Issue: 277231
Fixes: cf80ba6e2038 ("net/ixgbe: add support for representor ports")
