ANDROID: clear memory trylock-bit when page_locked.

Clearing trylock-bit of page shrinked by shrnk_page_list in advance
which avoids page in other scene with the trylock-bit.

The page with trylock-bit will be added ret_pages and handled in
trace_android_vh_handle_failed_page_trylock. If the page carried with
trylock-bit after unlocked by shrink_page_list will cause some error-issues
in other scene, so clear trylock-bit here.
trace_android_vh_page_trylock_get_result will clear trylock-bit and return
if page tyrlock failed in reclaim-process. Here we just want to clear
trylock-bit so that ignore page_trylock_result.

TODO: trace_android_vh_page_trylock_get_result should be changed to a
different hook which correctly reflects the usage here, which is to clear
the try-lock bit.

Fixes: 309a6bf8 ("ANDROID: vendor_hook: Add hook to not be stuck ro rmap lock in kswapd or direct_reclaim")
