hugetlbfs: correct handling of negative input to /proc/sys/vm/nr_hugepages

When the user inserts a negative value into /proc/sys/vm/nr_hugepages it
will cause the kernel to allocate as many hugepages as possible and to
then update /proc/meminfo to reflect this.

This changes the behavior so that the negative input will result in
nr_hugepages value being unchanged.
