Hangbin Liu cec74489a8 selftests/bpf/test_xdp_redirect_multi: use temp netns for testing 
Use temp netns instead of hard code name for testing in case the netns
already exists.

Remove the hard code interface index when creating the veth interfaces.
Because when the system loads some virtual interface modules, e.g. tunnels.
the ifindex of 2 will be used and the cmd will fail.

As the netns has not created if checking environment failed. Trap the
clean up function after checking env.

Fixes: 8955c1a329 ("selftests/bpf/xdp_redirect_multi: Limit the tests in netns")

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.
