tcp: set sw_if_index in tcp src-address cli

Browse Source 
the receive dpo added by tcp src-address cli do not have a valid sw_if_index ,
ip4_local_check_src() and tcp_input_lookup_buffer() will set ~0 to vnet_buffer(b)->sw_if_index[VLIB_RX],
which will cause crash in tcp46_reset_inline,

Type: fix
