Alexander Boettcher 869abe4ec6 NOVA: make noux_tool_chain happy
Multiple calls to get the dataspace capability on NOVA lead to the situation
that the caller gets each time a new mapping of the same capability at
different indexes.

The client/caller assumes to get every time the very same index, e.g. in
Noux the index is used to look up structures.

Cache the dataspace capability returned via a rm_session for base-nova.
