[IA64] Zero size /proc/vmcore on ia64

Browse source 
Set saved_max_pfn when discontig memory is in use.

This sets up saved_max_pfn when disctontig memory is in use.
This mirrors the code for contig memory.

This patch does not entirely solve the problem of making vmcore work,
however it does appear to be neccessary. Please consider applying.
