    netif: fix the netif's index error
    
    When using multiple netifs on one hardware interface (e.g. when mapping 
multiple IP addresses to one hardware interface), if the netif's low-level 
receive routine cannot decide for the correct netif, here the `netif` parameter 
may be a default netif, in this case, `p-> if_idx` will get a wrong netif index 
value. It should be placed after `netif = LWIP_ARP_FILTER_NETIF_FN(p, netif, 
lwip_htons(type));`.  Filter function can returns the correct netif before 
assigning `p-> if_idx`.
