powerpc: Fix oops on some machines due to incorrect pr_debug()
Recently, a patch left DEBUG enabled in the powerpc common PCI code, resulting in an old bug in a pr_debug() statement to show up and cause a NULL dereference on some machines. This fixes the pr_debug() statement and reverts to DEBUG not being force-enabled in that file. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
