misc: pci_endpoint_test: Handle 64-bit BARs properly
A 64-bit BAR consists of a BAR pair, where the second BAR has the
upper bits, so we cannot simply call pci_ioremap_bar() on every single
BAR index.
The second BAR in a BAR pair will not have the IORESOURCE_MEM resource
flag set. Only call ioremap on BARs that have the IORESOURCE_MEM
resource flag set.
