fs/cachefiles: Remove wait_bit_key layout dependency
commit 39f985c8f667c80a3d1eb19d31138032fa36b09e upstream.
Cachefiles was relying on wait_page_key and wait_bit_key being the
same layout, which is fragile. Now that wait_page_key is exposed in
the pagemap.h header, we can remove that fragility
A comment on the need to maintain structure layout equivalence was added by
Linus[1] and that is no longer applicable.
Fixes: 62906027091f ("mm: add PageWaiters indicating tasks are waiting for a page bit")
