arm64: mte: set VM_MTE_ALLOWED for hugetlbfs at correct place
The commit 5de195060b2e ("mm: resolve faulty mmap_region() error path
behaviour") moved vm flags validation before fop->mmap for file
mappings. But when commit 25c17c4b55de ("hugetlb: arm64: add mte support")
was rebased on top of it, the hugetlbfs part was missed. Mmapping
hugetlbfs file may not have MAP_HUGETLB set.
Fixes: 25c17c4b55de ("hugetlb: arm64: add mte support")
