Following scenario happens when prov is false and we have double free as
mentioned in the below

bluez-5.64/tools/mesh-gatt/prov-db.c:847: freed_arg: "g_free" frees 
"in_str".

bluez-5.64/tools/mesh-gatt/prov-db.c:867: double_free: Calling "g_free"
frees pointer "in_str" which has already been freed.
