mptcp: netlink: fix some error return code
Fix to return negative error code -EINVAL from some error handling
case instead of 0, as done elsewhere in those functions.
Fixes: 9ab4807c84a4 ("mptcp: netlink: Add MPTCP_PM_CMD_ANNOUNCE")
Fixes: 702c2f646d42 ("mptcp: netlink: allow userspace-driven subflow establishment")
