bcachefs: Key cache now works for snapshots btrees

Browse source

This switches btree_key_cache_fill() to use a btree iterator, not a
btree path, so that it can search for keys in previous snapshots.

We also add another iterator flag, BTREE_ITER_KEY_CACHE_FILL, to avoid
recursion back into the key cache.

This will allow us to re-enable the key cache for inodes in the next
patch.
