[PATCH] Fix pci_subsys_init() to have a return value

[David Howells <dhowells@redhat.com>]

Fix pci_subsys_init() to return a value (0) when it has finished.  All the
functions it calls currently return 0, so returning 0 here unconditionally
rather than gathering the results of its callees would seem reasonable.
