alpha/PCI: Call iomem_is_exclusive() for IORESOURCE_MEM, but not IORESOURCE_IO
The alpha pci_mmap_resource() is used for both IORESOURCE_MEM and IORESOURCE_IO resources, but iomem_is_exclusive() is only applicable for IORESOURCE_MEM. Call iomem_is_exclusive() only for IORESOURCE_MEM resources, and do it earlier to match the generic version of pci_mmap_resource().
