mptcp: fix subflow traversal at disconnect time
At disconnect time the MPTCP protocol traverse the subflows
list closing each of them. In some circumstances - MPJ subflow,
passive MPTCP socket, the latter operation can remove the
subflow from the list, invalidating the current iterator.
Address the issue using the safe list traversing helper
variant.
