llc: only change llc->dev when bind() succeeds

Author: Eric Dumazet
Author Date: 2022-06-21 19:09:00 UTC

llc: only change llc->dev when bind() succeeds

commit 2d327a79ee176930dc72c131a970c891d367c1dc upstream.

My latest patch, attempting to fix the refcount leak in a minimal
way turned out to add a new bug.

Whenever the bind operation fails before we attempt to grab
a reference count on a device, we might release the device refcount
of a prior successful bind() operation.

syzbot was not happy about this [1].

Note to stable teams:

Make sure commit b37a46683739 ("netdevice: add the case if dev is NULL")
is already present in your trees.
