selftests: mptcp: fix wait_rm_addr/sf parameters
commit 9168ea02b898d3dde98b51e4bd3fb082bd438dab upstream.
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.
