[PATCH] Fix memory leak in hugetlbfs

From: "Chen, Kenneth W" <kenneth.w.chen@intel.com>

The hugetlbfs_fill_super() doesn't free up memory allocated for sbinfo on
the way out in case of parsing error (and a few others).  This leads to
memory leak If root tries to mount a hugetlbfs with invalid mount option.
Here is a patch that fix the problem.
