[PATCH] procfs: Fix hardlink counts
The pid directories in /proc/ currently return the wrong hardlink count - 3,
when there are actually 4 : ".", "..", "fd", and "task".
This is easy to notice using find(1):
cd /proc/<pid>
find
In the output, you'll see a message similar to:
find: WARNING: Hard link count is wrong for .: this may be a bug in your
filesystem driver. Automatically turning on find's -noleaf option.
Earlier results may have failed to include directories that should have
been searched.

I also noticed that CONFIG_SECURITY can add a 5th: attr, and performed a
similar fix on the task directories too.
