Currently, we are calling guarded_list_destroy()
to destroy a mutex and then go ahead and use it through
delete_group
->delete_group__
->handle_flow_mod__
->run_rule_executes
->guarded_list_pop_all
The group related unit tests cause ovs-vswitchd to crash
because of this (on windows).
Calling guarded_list_destroy() after delete_group() solves the
problem.
