PCI: Protect restore with device lock to be consistent

Browse source

Commit b014e96d1a ("PCI: Protect pci_error_handlers->reset_notify() usage
with device_lock()") added protection around pci_dev_restore() function so
a device-specific remove callback does not cause a race condition with
hotplug.

pci_dev_lock() usage has been forgotten in two places.  Add locks for
pci_slot_restore() and moving pci_dev_restore() inside the locks for
pci_try_reset_function().
