ctdb-recoverd: Avoid duplicate recoverd event in parallel recovery

BUG: https://bugzilla.samba.org/show_bug.cgi?id=11956

In do_recovery, after the recovery and takeover is complete, recoverd
event is triggered.  When the parallel database recovery was separated,
ctdb_recovery_helper implemented sending END_RECOVERY control which
causes recoverd event to be triggered.  So when there is parallel database
recovery, recoverd event is triggered twice.

Instead move the call to run_recovered_eventscript() explicitly in
the serial recovery code path.  This avoids the duplication trigger of
recoverd event.
