Wifi-Hal: Set nl socket's local port with nl api

The nl library maintains one local port pool for nl sockets, one
port is occupied when new nl socket is allocated and it needs to
released, otherwise the nl socket allocation will fail since no
local port can be used in nl socket allocation.
Wifi hal sets own local port for nl socket directly without
calling api and causes leak.
