    etharp: cast netif_addr_idx_t to u16_t to match format type
    
    This fixes an issue seen on MacOS with Clang 9.0.0:
    
    ../../../../lwip/src/core/ipv4/etharp.c:1069:142: error: format specifies type 'unsigned short' but the argument has type 'netif_addr_idx_t'
          (aka 'unsigned char') [-Werror,-Wformat]
            LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_query: dropped previously queued packet %p for ARP entry %"U16_F"\n", (void *)q, i));
            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~
    
    ../../../../lwip/src/core/ipv4/etharp.c:1074:120: error: format specifies type 'unsigned short' but the argument has type 'netif_addr_idx_t'
          (aka 'unsigned char') [-Werror,-Wformat]
          LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_query: queued packet %p on ARP entry %"U16_F"\n", (void *)q, i));
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~
    
    By default, netif_addr_idx_t is u8_t, so cast up to u16_t to match the format type
