autofs-5.0.8 - fix negative status being reset on map read

From: Ian Kent <raven@themaw.net>

The map entry status field, which holds the negative cache timeout,
gets reset on a map re-read.

If the negative map entry was added at the same time as the map
read and it was for an entry that was never in the map, the
status gets reset even though the entry is still a valid
negative entry.

Consequently lookups for non-existent map entries are never
seen as negative and the lookup always continues.
