[PATCH] Clear ListenTransConns entries in CloseWellKnownConnections

[Alan Coopersmith]

Since _XSERVTransClose frees the connection pointer passed to it,
remove that pointer from the array, so we don't try to double free it
if we come back into CloseWellKnownConnections again.

Should fix https://bugzilla.yoctoproject.org/show_bug.cgi?id=6665 in which
the shutdown section of the main() loop called CloseWellKnownConnections()
and then moved on to ddxGiveUp(), which failed to release the VT and thus
called AbortServer(), which called CloseWellKnownConnections() again.
