We can enter the main mptcp_recvmsg() loop even when
no subflows are connected. As note by Eric, that would
result in a divide by zero oops on ack generation.
Address the issue by checking the subflow status before
sending the ack.
Additionally protect mptcp_recvmsg() against invocation
with weird socket states.
v1 -> v2:
- removed unneeded inline keyword - Jakub
