selftests: mptcp: diag: check CURRESTAB counters

Browse Source 
commit 81ab772819da408977ac79c0a17d8be57283379f upstream.

This patch adds a new helper chk_msk_cestab() to check the current
established connections counter MIB_CURRESTAB in diag.sh. Invoke it
to check the counter during the connection after every chk_msk_inuse().
