[PATCH 27/39] mm: rename is_vm_hugetlb_page() to vma_is_hugetlb()

["Lorenzo Stoakes (ARM)" <ljs@kernel.org>]

The is_vm_hugetlb_page() predicate is badly named - the mapping can span
more than a page and it is inconsistent with other VMA predicates that
typically are prefixed by vma_.

Rename to vma_is_hugetlb() for consistency, and while we're here update
some VM_BUG_ON_VMA() to VM_WARN_ON_ONCE_VMA() as to avoid unnecessary
oopses.

No functional change intended.
