Bug #24585978 INNODB: ASSERTION TOTAL_RECS > 0 FAILURE IN FILE DICT0STATS.CC

Analysis:
========
 There was missing bracket for IF conditon in dict_stats_analyze_index_level()
and it leads to wrong result.

====
 Fix the IF condition in dict_stats_analyze_index_level() so that it satisfied
the if condtion only if level is zero.
