coverity/102149: Out-of-bounds access: FP.

Browse Source 
Problem    : Out-of-bounds access @ 5815.
Diagnostic : False positive.
Rationale  : Error occurs when event_name2nr() returns NUM_EVENTS, which
             means an event with that name was not found. That cannot
             happen, as previous check using find_end_event() @ 5744
             ensures event name exists.
Resolution : Assert event_name2nr() result is less thatn NUM_EVENTS.
