[PATCH 3/4] rpc.gssd: handle error to open toplevel directory

["J. Bruce Fields" <bfields@redhat.com>]

From: "J. Bruce Fields" <bfields@redhat.com>

Reverse the sense of the test here, and also add debugging and cleanup
in the error case.

(Though the lack of cleanup isn't currently a problem in practice since
we'll eventually exit in this case.)
