commit f3efb9569b4a21354ef2caf7ab0608a3e14cc6e4 upstream.
The commit a4e772898f8b ("PCI: Add missing bridge lock to pci_bus_lock()")
made the lock function to call depend on dev->subordinate but left
pci_slot_unlock() unmodified creating locking asymmetry compared with
pci_slot_lock().
Because of the asymmetric lock handling, the same bridge device is unlocked
twice. First pci_bus_unlock() unlocks bus->self and then pci_slot_unlock()
will unconditionally unlock the same bridge device.
Move pci_dev_unlock() inside an else branch to match the logic in
pci_slot_lock().
Fixes: a4e772898f8b ("PCI: Add missing bridge lock to pci_bus_lock()")
