[PATCH] Clear reused error variable

[Guido Günther <agx sigxcpu org>]

Hi,

vnc_connection_connect_socket reuses an error variable without clearing
it (issued by g_socket_connect in vnc_connection_connect_socket):

(gvncviewer:20406): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Connection in progress
Failed to connect to server

Attached patch fixes it for me.
Cheers,
 -- Guido
