Subject: [PATCH] NVIDIA: fix wrong number of threads
In the cuda backend for monero we start always twice as much threads as needed.
Those threads are than removed after the AES matrix is copied to the shared memory.
Never the less it is the result of an copy past bug.
- start correct number of threads for `monero`
