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. In the progress[unlock_page, handled],
the page carried with trylock-bit 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.
