Currently the page_frag API is returning 'virtual address'
or 'va' when allocing and expecting 'virtual address' or
'va' as input when freeing.
As we are about to support new use cases that the caller
need to deal with 'struct page' or need to deal with both
'va' and 'struct page'. In order to differentiate the API
handling between 'va' and 'struct page', add '_va' suffix
to the corresponding API mirroring the page_pool_alloc_va()
API of the page_pool. So that callers expecting to deal with
va, page or both va and page may call page_frag_alloc_va*,
page_frag_alloc_pg*, or page_frag_alloc* API accordingly.
