autofs-5.0.3 - nisplus partial and free

From: Jeff Bastian <jbastian@redhat.com>

During a nisplus key lookup nis_list() can return NIS_PARTIAL
as well as possibly NIS_NOTFOUND or NIS_S_NOTFOUND when the key
doesn't exist. This patch adds this to the checks and fixes a use
after free of the result struct.
