opensm/osm_state_mgr.c: Don't signal DISCOVER to SM state machine when already DISCOVERING

Eliminate this "illegal" state machine transition which triggers the following log message:

sm_state_mgr_signal_error: ERR 3207: Invalid signal OSM_SM_SIGNAL_DISCOVER in state DISCOVERING

This is observed when the SM port is down.
