(cherry picked from commit 3ee5234df68d253c415ba4f2db72ad250d9c21a9)

The red-black node node in the ceph osd event structure is not
initialized in create_osdc_create_event(). Because this node can
be the subject of a RB_EMPTY_NODE() call later on, we should ensure
the node is initialized properly for that.
