This adds proper locking for the function, b43_op_beacon_set_tim in main.c by using the mutex lock in the structure pointer wl, as embedded into this pointer as a mutex in order to protect against multiple access to the pointer wl when updating the templates for this pointer in the function, b43_update_templates internally in the function, b43_op_beacon_set_tim.
