autofs4-2.6.34-rc1 - fix link_count usage

After commit 1f36f774 ("Switch !O_CREAT case to use of do_last()") in
2.6.34-rc1 autofs direct mounts stopped working.  This is caused by
current->link_count being 0 when ->follow_link() is called from
do_filp_open().

I can't work out why this hasn't been seen before Als patch series.

This patch removes the autofs dependence on current->link_count.
