Subject: [PATCH] Bug #17297012 MEMORY LEAK IN MYSQL_OPTIONS WHILE CALLING
WITH OPTION MYSQL_SET_CLIENT_IP
Memory Leak in mysql_options() was caused by missing call
to my_free() in MYSQL_SET_CLIENT_IP branch. Fixed by adding
my_free() to cleanup mysql->options.client_ip value before
assigning new value.
