From: Geliang Tang <geliang.tang@xxxxxxxx>
The second input parameter of 'wait_rm_addr/sf $1 1' is misused. If it's
1, wait_rm_addr/sf will never break, and will loop ten times, then
'wait_rm_addr/sf' equals to 'sleep 1'. This delay time is too long,
which can sometimes make the tests fail.
A better way to use wait_rm_addr/sf is to use rm_addr/sf_count to obtain
the current value, and then pass into wait_rm_addr/sf.
Fixes: 4369c198e599 ("selftests: mptcp: test userspace pm out of transfer")
