This patch adds a new helper chk_subflows_total(), in it use the newly
added counter mptcpi_subflows_total to get the "correct" amount of
subflows, including the initial one. To be compatible with old 'ss'
version without this counter, get the total subflows using this 'ss'
command:
ss -ti | grep -c tcp-ulp-mptcp.
