Adds proper locking for the function, b43_op_beacon_set_tim in main.c that
internally calls b43_update_templates.
Due to the function that is being called internally,b43_update_templates
needing the mutex lock of the structure
pointer wl passed it to run successfully and without issues we add the calls
to mutex_lock before and mutex_unlock
after it's call internally in b43_op_beacon_set_tim in order to allow the
function,,b43_update_templates to run
successfully and without issues related to concurrent access.
