[IA64] Update Altix BTE error return status patch

I neglected to send Tony the most recent version of the
patch ("Fix Altix BTE error return status") applied
as commit: 64135fa97ce016058f95345425a9ebd04ee1bd2a

This patch gets it up to date.  Without this patch
on shub2, if there is no error xpcBteUnmappedError is
returned instead of xpcSuccess.
