Memory Leak in bag_del_all function of src/mixer/bag.c

alsa-project/alsa-lib issue #453 was reopened from zkh8227:

#Issue Summary The bag_del_all function in src/mixer/bag.c has a memory leak. It removes elements from a linked list but doesn't free the memory allocated for them in bag_add function, which uses malloc. Repeated calls to bag_add and bag_del_all will waste memory. #Fix Suggestion Change bag_del_all to free memory when removing elements.
