In single-link usage, the function tipc_node_timeout() still iterates over the whole link array to handle each link. Given that the maximum number of bearers are 3, there are 2 redundant iterations with lock grab/release. Since this function is executing very frequently it makes sense to optimize it. This commit adds conditional checking to exit from the loop if the known number of configured links has already been accessed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
