[POWERPC] pseries: Print PCI slot location code on failure
The PCI error recovery code will printk diagnostic info when a PCI error event occurs. Change the messages to include the slot location code, which is how most sysadmins will know the device. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
