Only announce IV_NCP=2 when we are willing to support these ciphers

We currently always announce IV_NCP=2 when we support these ciphers even
when we do not accept them. This lead to a server pushing a AES-GCM-128
cipher to clients and the client then rejecting it.

Patch V2:  Remove unecessary restoring of ncp_ciphers
Patch V3:  Do not add ncp_ciphers in context
