ceph: don't pre-allocate space for cap release messages
Previously we pre-allocate cap release messages for each caps. This wastes lots of memory when there are large amount of caps. This patch make the code not pre-allocate the cap release messages. Instead, we add the corresponding ceph_cap struct to a list when releasing a cap. Later when flush cap releases is needed, we allocate the cap release messages dynamically.
