staging: android: ion: Cleanup ion_page_pool_alloc_pages

Browse Source 
ion_page_pool_alloc_pages calls alloc_pages to allocate pages for page
pools. If alloc_pages return NULL, it will return NULL, or it will
return the pages allocate from alloc_pages. So we can just return
alloc_pages without any judgement.
