[IPV6]: return EINVAL for invalid address with flowlabel lease request
Currently, when an application requests a lease for a flowlabel via the IPV6_FLOWLABEL_MGR socket option, no error is returned if an invalid type of destination address is supplied as part of the request, leading to a silent failure. This patch ensures that EINVAL is returned to the application in this case. Signed-off-by: James Morris <jmorris@namei.org> Signed-off-by: David S. Miller <davem@davemloft.net>
