[PATCH 2.6.13-rc2] pci: fix PCI && !HOTPLUG compile error

[Mikael Pettersson <mikpe@csd.uu.se>]

2.6.13-rc2 triggers compile errors in pci-driver.c
when hotplug is disabled:

drivers/pci/pci-driver.c: In function 'pci_match_device':
drivers/pci/pci-driver.c:156: error: dereferencing pointer to incomplete type
drivers/pci/pci-driver.c:156: warning: type defaults to 'int' in declaration of 'type name'
drivers/pci/pci-driver.c:156: error: request for member 'node' in something not a structure or union
drivers/pci/pci-driver.c:156: warning: type defaults to 'int' in declaration of '__mptr'
drivers/pci/pci-driver.c:156: warning: initialization from incompatible pointer type
etc

This is because 2.6.13-rc2 added a code block to this function which references
hotplug-only stuff. Fixed crudely by #ifdef CONFIG_HOTPLUG around it.
