passthrough_ll: Use cache_readdir for directory open (#492)

Upstreamed from:
  https://www.redhat.com/archives/virtio-fs/2020-January/msg00106.html

Since keep_cache(FOPEN_KEEP_CACHE) has no effect for directory as
described in fuse_common.h, use cache_readdir(FOPEN_CACHE_DIR) for
diretory open when cache=always mode.
