[dpdk-dev] [PATCH] net/ixgbe: fix default MAC setting

Pool 0 is not PF, it's VF 0. So the MAC is set for VF 0
but not PF.
The code introduced a weird issue. In the scenario PF + VF,
when only starting PF, the default PF MAC address is working.
But after starting a VF, the default PF MAC address becomes
the VF's address.
Use the pool which is not occupied by VFs for PF to fix it.
Fixes: 8164fe82846b ("ixgbe: add default mac address modifier")
