Fix blocking close with LWIP_SO_SNDTIMEO

Browse Source 
This fixes a bug in close when LWIP_SO_SNDTIMEO is enabled, but
the option is not in use on the socket

A simple mis-typed comparison against zero would cause the close_timeout
to get set to zero if conn->send_timeout was 0

The intended check was to over-ride the default close timeout if a
send timeout had been specified via SO_SNDTIMEO
