Commit Message

In the end of the test, there will be an error message induced by the
`ip netns del ns1` command in cleanup()

  Tests passed: 201
  Tests failed:   0
  Cannot remove namespace file "/run/netns/ns1": No such file or directory

Redirect the error message to /dev/null to mute it.

Fixes: a0e11da78f48 ("fib_tests: Add tests for metrics on routes")

I don't think this tag is correct. More likely that this is caused by
commit b60417a9f2b8 ("selftest: fib_tests: Always cleanup before exit").

You can even reproduce it with '-h':

# ./fib_tests.sh -h
usage: fib_tests.sh OPTS
[...]
Cannot remove namespace file "/var/run/netns/ns1": No such file or directory

Reverting the commit I mentioned makes it go away.

Also, please use "PATCH net" prefix:
