Wang Hai 9414855a13 ipv6: addrlabel: fix possible memory leak in ip6addrlbl_net_init 
[ Upstream commit e255e11e66da8281e337e4e352956e8a4999fca4 ]

kmemleak report a memory leak as follows:

unreferenced object 0xffff8880059c6a00 (size 64):
  comm "ip", pid 23696, jiffies 4296590183 (age 1755.384s)
  hex dump (first 32 bytes):

    [<0000000099df30e7>] entry_SYSCALL_64_after_hwframe+0x44/0xa9

We should free all rules when we catch an error in ip6addrlbl_net_init().
otherwise a memory leak will occur.

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.
