vxlan: add check to prevent use of remote ip attributes with NDA_NH_ID

Browse source

NDA_NH_ID represents a remote ip or a group of remote ips.
It allows use of nexthop groups in lieu of a remote ip or a
list of remote ips supported by the fdb api.

Current code ignores the other remote ip attrs when NDA_NH_ID is
specified. In the spirit of strict checking, This commit adds a
check to explicitly return an error on incorrect usage.
