Wang Hai fa6882c636 tipc: fix memory leak in tipc_topsrv_start() 
kmemleak report a memory leak as follows:

unreferenced object 0xffff88810a596800 (size 512):
  comm "ip", pid 21558, jiffies 4297568990 (age 112.120s)
  hex dump (first 32 bytes):

'srv' is malloced in tipc_topsrv_start() but not free before
leaving from the error handling cases. We need to free it.

README 

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.

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.
