ixgbe: fix PF promiscuous mode after VF closed

There's an issue reported. In the scenario DPDK PF + DPDK VF,
if the VF port is closed, PF port cannot receive packets.
I found at that time the promicuous mode is disabled on the PF
port. But it should be enabled.
When VF port is closed, it will send a message to its PF port to
reset it. During this, PF port will also reset its own
promicuous mode. Which promiscuous mode should be set depends on
the parameter stored in the device data. In the function
set_rx_mode, the pointer of device data points to the wrong
address. So, the promiscuous mode is wrong.
