selftests: test_vxlan_under_vrf: mute unnecessary error message

Browse Source 
The cleanup function in this script that tries to delete hv-1 / hv-2
vm-1 / vm-2 netns will generate some uncessary error messages:

Cannot remove namespace file "/run/netns/hv-2": No such file or directory
Cannot remove namespace file "/run/netns/vm-1": No such file or directory
Cannot remove namespace file "/run/netns/vm-2": No such file or directory

Redirect it to /dev/null like other commands in the cleanup function
to reduce confusion.
