mptcp: Fix IPv6 reqsk ops and some netlink error codes
Patch 1 adds some missing error status values for MPTCP path management
netlink commands with invalid attributes.
Patches 2-4 make IPv6 subflows use the correct request_sock_ops
structure and IPv6-specific destructor. The first patch in this group is
a prerequisite change that simplifies the last two patches.
