Do not use hugepages if none are available.

In case socket-mem was set to <1024 and no 1G page long hupepages were
available, the condition was evaluated in unexpected manner. In other
words use_1g == 1, and that fails later in mount().
This patch makes sure this is prevented - if there are no pages_available,
do not even try to use that pagesize.
