David Miller d67afe5ed0 [PATCH] pci: don't try to remove sysfs files before they are setup.
The PCI sysfs attributes are created after the initial PCI bus scan.  With
the addition of more return value checking and assertions in the device and
sysfs layers we now can get dumps like this on sparc64:

[   20.135032] Call Trace:

[   20.135514] PCI0(PBMB): Bus running at 33MHz

It's triggering because removal of the "config" PCI sysfs file for the
device fails.

On sparc64, after probing the device, we'll delete the PCI device via
pci_remove_bus_device() if we cannot find the firmware device tree node
corresponding to it.

This is fine, but at this point the sysfs files for the PCI device won't be
setup yet.

So we should not try to do anything in pci_remove_sysfs_dev_files() if
pci_sysfs_init() has not run yet.
