bgpd: BGP_ERR_MULTIPLE_INSTANCE_NOT_SET is an impossible condition

Browse source 
This code is not returned anywhere in the system as that bgp
is by default multiple-instance 'only' now.  So remove
the last remaining bits of it from the code base.

Remove BGP_ERR_MULTIPLE_INSTANCE_USED too.

Make bgp_get explicitly return BGP_SUCCESS
instead of 0.

Remove the multi-instance error code too.
