PCI: Warn about failures instead of "must_check" functions
These places capture return values to avoid "must_check" warnings, but we didn't *do* anything with the return values, which causes "set but not used" warnings. We might as well do something instead of just trying to evade the "must_check" warnings. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
