hugetlbfs: return negative error code for bad mount option
This fixes the following BUG:
# mount -o size=MM -t hugetlbfs none /huge
hugetlbfs: Bad value 'MM' for mount option 'size=MM'
------------[ cut here ]------------
kernel BUG at fs/super.c:996!
Due to
BUG_ON(!mnt->mnt_sb);
in vfs_kern_mount().
Also, remove unused #include <linux/quotaops.h>
