[pgpool-committers: 968] pgpool: Fix wd_create_send_socket() not to execute select() before conn

[Yugo Nagata]

Fix wd_create_send_socket() not to execute select() before connect().

How select() works on an unconnected socket is undefined, and differs
between platform. This returns 2 on Linux and it is eventually harmless.
However, this returns 0 on Solaris and it is indistinguishable from
timeout.
