Suren Baghdasaryan 23fb3111f6 ANDROID: page_pinner: prevent pp_buffer access before initialization ...

If page_pinner is configured with page_pinner_enabled=false and
failure_tracking=true, pp_buffer will be accessed without being
initialized. Prevent this by adding page_pinner_inited checks in
functions that access it.
