    net/radix: Simplify mask manipulation in rn_addmask()
    
    Since the max key length is known, so use an on-stack variable instead
    of memory allocation for the 'addmask_key' variable.  Therefore also get
    rid of the 'rnh_last_zeroed' member from 'radix_node_head' struct.
    Rename 'rnh_last_zeroed' to its origin 'rnh_addrsize' instead of
    removing it.
