Markus Armbruster fdceb4ab4d io: Fix qio_channel_socket_close() error handling 
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

qio_channel_socket_close() passes @errp first to
socket_listen_cleanup(), and then, if closesocket() fails, to
error_setg_errno().  If socket_listen_cleanup() failed, this will trip
the assertion in error_setv().

Fix by ignoring a second error.
