pci: Update the highest subordinate bus number for bridge setup
Update the highest subordinate bus number after probing the devices
under the bus for setting up the bridge correctly.
The commit 42f3663a3f67 ("pci: Update to use new sequence numbers")
removed this but it is required if a PCIe bridge is under the bus.
Fixes: 42f3663a3f67 ("pci: Update to use new sequence numbers")
