ANDROID: mm/shmem: fix trace hook used to get the shmem folio

Browse Source 
Before mTHP for shmem is added, there used different API for huge and
order-0 folios. With mTHP, shmem_alloc_folio() is used for both and is
differentiated at the order passed.

To make better decission at the client, pass the order.
