[PATCH] autofs4: autofs4_follow_link false negative fix

Browse Source 
The check for an empty directory in the autofs4_follow_link method fails
occassionally due to old dentrys.  We had the same problem
autofs4_revalidate ages ago.  I thought we wouldn't need this in
autofs4_follow_link, silly me.
