Support calling map_update_elem() from the datapath programs by calling into FW-provided helper. Value pointer is passed in LM pointer #2. Keeping track of old state for arg3 is not necessary, since LM pointer #2 will be always loaded in this case, the trivial optimization for value at the bottom of the stack can't be done here.
