When user insert negative value into /proc/sys/vm/nr_hugepages it will

in the setting a random number of HugePages in system (can be easily showed
at /proc/meminfo output). This patch fixes the wrong behavior so that the

v2: same fix was also done in hugetlb_overcommit_handler function
as suggested by reviewers.
