genl: Update mt_id of cache ops when resolving genl id

Browse source 
The cache layer uses the message type array stored in the cache
ops to lookup which cache a message belongs to. Update to the
the message array with the resolved generic netlink id to make
it compatible with the caching API.

Allows to use nl_cache_refill() and others for generic netlink
based caches with dynamic generic netlink ids.
