hugetlb: update vma flag check for hugetlb vma lock
The check for whether a hugetlb vma lock exists partially depends on the
vma's flags. Currently, it checks for either VM_MAYSHARE or VM_SHARED.
The reason both flags are used is because VM_MAYSHARE was previously
cleared in hugetlb vmas as they are tore down. This is no longer the
case, and only the VM_MAYSHARE check is required.
