Description

I disabled bluestore/rocksdb cache to estimate ceph-osd's memory consumption
by set bluestore_cache_size_ssd/bluestore_cache_size_hdd/bluestore_cache_size to 0.

This caused a rocksdb error:

 2018-04-19 10:24:29.444 7f6926908240 -1 bluestore(/var/lib/ceph/osd/ceph-0/) _read_fsid unparsable uuid

So, if block cache is disabled, we should not set cache_index_and_filter_blocks.
