rpc: Check and message setsockopt()

Browse Source 
Check status when attempting to set SO_REUSEADDR flag on outgoing connection
On failure, VIR_WARN(), but continue to connect. This code path is on the
sender side where the setting is just a hint and would only take effect if
the sender is overflowed with TCP connections.  Inability to set doesn't mean
failure to establish a connection.
