[PATCH] appletalk: Fix atalk_proc_init() return path

[PATCH] appletalk: Fix atalk_proc_init() return path

[Lukas Wunner]

From: Vincent Duvert <vincent.ldev@duvert.net>

Add a missing return statement to atalk_proc_init so it doesn't return
-ENOMEM when successful.  This allows the appletalk module to load
properly.

Fixes: e2bcd8b0ce6e ("appletalk: use remove_proc_subtree to simplify procfs code")

Shows how many people are actually using appletalk if it doesn't even
load since v5.1

Applied.
