sgi-xpc: XPC fails to discover partitions with all nasids above 128

commit c22c7aeff69796f46ae0fcec141538e28f50b24e upstream.

UV hardware defines 256 memory protection regions versus the baseline 64
with increasing size for the SN2 ia64.  This was overlooked when XPC was
modified to accomodate both UV and SN2.

Without this patch, a user could reconfigure their existing system and
suddenly disable cross-partition communications with no indication of what
has gone wrong.  It also prevents larger configurations from using
cross-partition communication.
