autofs-5.0.7 - fix submount offset delete

From: Ian Kent <ikent@redhat.com>

As part of the implementation to allow for limited update of
the internal hosts map by using a HUP signal some code that
deleted any offset entries from the cache on lookup was removed
as it appeared to not be needed.

There is however a case where it is needed to avoid a duplicate
cache entry failure on lookup.
