[PATCH] makedumpfile: Copy correct nr_cpus info to dumpfile during re-filtering

[Mahesh J Salgaonkar]

From: Mahesh Salgaonkar <mahesh at linux.vnet.ibm.com>

During re-filtering nr_cpus is to 0 in the o/p dumpfile and hence crash
utility fails to open the re-filtered dumpfile.

This patch fixes this issue by copying nr_cpus info from kdump-compressed
dumpfile to info->nr_cpus which then get's correctly copied to o/p
dumpfile.
