mptcp: correct MPTCP_SUBFLOW_ATTR_SSN_OFFSET reserved size
ssn_offset field is u32 and is placed into the netlink response with
nla_put_u32(), but only 2 bytes are reserved for the attribute payload
in subflow_get_info_size() (even though it makes no difference
in the end, as it is aligned up to 4 bytes). Supply the correct
argument to the relevant nla_total_size() call to make it less
confusing.
Fixes: 5147dfb50832 ("mptcp: allow dumping subflow context to userspace")
