lib: dont be tricky with session_id just make it a session_id

Browse Source 
- Previously was substituting a pointer to local allocated session for the
session_id returned from the FE adapter. This complexity isn't needed.
- Get rid of "%llu" format and the casts that came with it, instead use PRIu64
and the actual (uint64_t) type.
