mm: Allow GFP_ACCOUNT to be used in alloc_pages_nolock().

Change alloc_pages_nolock() to default to __GFP_COMP when allocating
pages, since upcoming reentrant alloc_slab_page() needs __GFP_COMP.
Also allow __GFP_ACCOUNT flag to be specified,
since most of BPF infra needs __GFP_ACCOUNT except BPF streams.
