Make sure that cr_error is set to ESHUTDOWN when closing the connection.

Browse Source 
This is normally done by a loop in clnt_dg_close(), but requests that aren't
in the pending queue at the time of closing, don't get set. This avoids a
panic in xdrmbuf_create() when it is called with a NULL cr_mrep if
cr_error doesn't get set to ESHUTDOWN while closing.
