efi/fb: Correct PCI_STD_RESOURCE_END usage
PCI_STD_RESOURCE_END is (confusingly) the index of the last valid BAR, not the *number* of BARs. To iterate through all possible BARs, we need to include PCI_STD_RESOURCE_END. Fixes: 55d728a40d36 ("efi/fb: Avoid reconfiguration of BAR that covers the framebuffer") Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
