[PATCH net-next 2/6] selftests: net: remove redundant rp_filter configuration

[Hangbin Liu <liuhangbin@gmail.com>]

The following tests use setup_ns to create a network namespace, which
will disables rp_filter immediately after namespace creation. Therefore,
it is no longer necessary to disable rp_filter again within these individual
tests.
