[PATCH] ctdb-daemon: Free up record data if a call request is deferred (bug 13029)

If a call request for a key (migration request) is in flight, then all
the subsequent call requests for the same key are deferred. In that case,
the data corresponding to key read from the local tdb is useless and there
is no need to keep it around. Once the deferred call is reprocessed,
the data corresponding to that key will be fetched again.
For smb workload with lots of contention, this can result in
CTDB consuming gigabytes of memory.
Please review and push.
