sparc64: Fix crash with /proc/iomem

When you compile kernel on Sparc64 with heap memory checking and type
"cat /proc/iomem", you get a crash, because pointers in struct
resource are uninitialized.

Most code fills struct resource with zeros, so I assume that it is
responsibility of the caller of request_resource to initialized it,
not the responsibility of request_resource functuion.

After 2.6.29 is out, there could be a check for uninitialized fields
added to request_resource to avoid crashes like this.
