PCI: pciehp: Use is_pciehp instead of is_hotplug_bridge
The PCIe hotplug driver calculates the depth of a nested hotplug port by
looking at the is_hotplug_bridge flag. The depth is used as lockdep class
to tell hotplug ports apart.
The is_hotplug_bridge flag encompasses ACPI slots handled by the ACPI
hotplug driver, hence the calculated depth may be too high. Avoid by
checking the is_pciehp flag instead.
This glitch likely has no user-visible impact: ACPI slots typically only
exist at the Root Port level, not in nested hotplug hierarchies. Also,
CONFIG_LOCKDEP is usually only used by developers. So this is just for
the sake of correctness.
