x86/PCI: Abort if legacy init fails

Browse source 
If the legacy PCI init fails, then there are no PCI config space accesors
available, but the code continues and tries to scan the busses, which fails
due to the lack of config space accessors.

Return right away, if the last init fallback fails.

Switch the few printks to pr_info while at it.
