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.
Please apply.
