Subject: [PATCH] nodeinfo: fix nodeGetFreePages when max node is zero

https://bugzilla.redhat.com/show_bug.cgi?id=1145048

In nodeGetFreePages, if startCell is given by '0',
and the max node number is '0' too. The for-loop
wouldn't be executed.
So convert it to while-loop.

Before:
> virsh freepages --cellno 0 --pagesize 4
error: internal error: no suitable info found

After:
> virsh freepages --cellno 0 --pagesize 4
