[PATCH v2 net 2/4] selftests: net: fix setup_ns usage in rtnetlink.sh

[Paolo Abeni]

The setup_ns helper marks the testns global variable as
readonly. Later attempts to set such variable are unsuccessful,
causing a couple test failures.

Avoid completely the variable re-initialization and let the
function access the global value.

Fixes: ("selftests: rtnetlink: use setup_ns in bonding test")
