PCI: Fix pci_slot_lock () device locking

Browse source

[ Upstream commit 1f5e57c622 ]

Like pci_bus_lock(), pci_slot_lock() needs to lock the bridge device to
prevent warnings like:

  pcieport 0000:e2:05.0: unlocked secondary bus reset via: pciehp_reset_slot+0x55/0xa0

Take and release the lock for the bridge providing the slot for the
lock/trylock and unlock routines.
