autofs-5.0.1 - clear rpc client on lookup fail

From: Ian Kent <raven@themaw.net>

If a name lookup failure occurs in create_tcp_client() or create_udp_client()
the client is destoryed and the file descriptor is closed at exit but the rpc
client isn't set to NULL. This leads to a subsequent SEGV when attempting to
use the invalid client.
