efi/fb: Correct PCI_STD_RESOURCE_END usage



[ Upstream commit 92a16c86299c64f58f320e491977408ba31b8c3c ]

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")
