PCI: Fix pci_slot_lock () device locking
[ Upstream commit 1f5e57c622b4dc9b8e7d291d560138d92cfbe5bf ]
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.
