mm: change to return bool for isolate_lru_page()
The isolate_lru_page() can only return 0 or -EBUSY, and most users did not
care about the negative error of isolate_lru_page(), except one user in
add_page_for_migration(). So we can convert the isolate_lru_page() to
return a boolean value, which can help to make the code more clear when
checking the return value of isolate_lru_page().
Also convert all users' logic of checking the isolation state.
No functional changes intended.
