socket_watcher_start: Silence conversion warning for sin(6)_port

Browse Source 
Although in_port_t is a typedef for uint16_t, GCC in Ubuntu 12.04
complains about potential loss of data due to converting int to
uint16_t.  Since we know this isn't possible, silence the warning to
avoid breaking QB until it gets upgraded to a newer Ubuntu.
