network: also check SR-IOV PF port and other VF ports before configuring

When a PF port becomes down (this can happens e.g. the PF port is joining
a bond interface), some drivers make its VF ports also become down, and
may cause failures in configuring VF ports.

Similary, when a VF port become down, some drivers make its PF port and
other VF ports down.

Let's configure SR-IOV ports (both PF and VFs) after all link-layer
settings of all ports being applied.

Fixes #23315.
