mptcp: add TCP_INQ cmsg support
Support the TCP_INQ setsockopt.
This is a boolean that tells recvmsg path to include the remaining
in-sequence bytes in the cmsg data.
v2: do not use CB(skb)->offset, increment map_seq instead (Paolo Abeni)
v3: adjust CB(skb)->map_seq when taking skb from ofo queue (Paolo Abeni)
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/224
