Nathan Hartman 6c4bd5c5ef net: Fix memcpy() size used by SIOCSIFHWADDR for radios 
* net/netdev/netdev_ioctl.c:
  (netdev_ifr_ioctl): The ioctl SIOCSIFHWADDR sets the hardware address
   (e.g., Ethernet MAC, etc.) of a network interface. Radio devices may
   have different lengths of hardware addresses, such as
   NET_6LOWPAN_EADDRSIZE (8), NET_6LOWPAN_SADDRSIZE (2), or
   RADIO_MAX_ADDRLEN (8). Also, Kconfig CONFIG_PKTRADIO_ADDRLEN allows
   the user to set any arbitrary size. Note that while the sister ioctl
   SIOCGIFHWADDR "get hardware address" copies
   `dev->d_mac.radio.nv_addrlen` bytes, SIOCSIFHWADDR was copying
   NET_6LOWPAN_ADDRSIZE bytes unconditionally. Depending on which radio
   is used, this could be incorrect. Fixing it to use
   `dev->d_mac.radio.nv_addrlen` for SIOCSIFHWADDR as well. Also adding
   DEBUGASSERT to ensure this is within bounds of source and
   destination of the copy.
