[PATCH] gssd: Error out when rpc_pipefs directory is empty

[Steve Dickson <steved@redhat.com>]

When there is no kernel modules loaded the rpc_pipefs
directory is empty, which cause rpc.gssd to silently
exit.

This patch adds a check to see if the topdirs_list
is empty. If so error out without dropping a core.
