Subject: [PATCH net 4/5] selftests: mptcp: update userspace pm subflow
 tests

From: Geliang Tang <geliang.tang@...e.com>

To align with what is done by the in-kernel PM, update userspace pm
subflow selftests, by sending the a remove_addrs command together
before the remove_subflows command. This will get a RM_ADDR in
chk_rm_nr().

Fixes: 5e986ec46874 ("selftests: mptcp: userspace pm subflow tests")
