patch needed for windows apr_socket_send()

[Chris Demetriou]

when an error occurs, *len isn't set to 0 (as is done for all other targets).

looked over all the other send/recv calls in the windows code, i
didn't notice others that were missing.

(found it doing non-blocking I/O when the receiver wasn't reading its
data and the socket buffer filled.)
