[PATCH] switch autofs4 to touch_atime()

Browse Source 
After my lookup_hash patch ->d_revalidate always gets a valid struct nameidata
passed (unless you use lookup_one_len which autofs4 doesn't), so we can switch
it from update_atime to touch_atime.  This is a bit of an academic excercise
because autofs has a 1:1 vfsmount superblock relation, but I want to get rid
of update_atime so filesystems authors can't easily screw up per-mountpoint
noatime support.
