xen/pcifront: Use global PCI rescan-remove locking

Multiple race conditions are possible between the Xen pcifront device
addition and removal and the generic PCI device addition and removal that
can be triggered via sysfs.

To avoid those race conditions make the Xen pcifront code use global PCI
rescan-remove locking.
