NVIDIA: fix wrong number of threads

Update for upcoming Graft CNv2 fork

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`

release 2.5.1

Add console warning on GPU error.

reduce blocking during metric update

fix broken AMD OpenCL compile

fix access uninitialized value

The AMD compiler for OpenCL shipped with the driver 14XX is broken
and can not compile xmr-stak since the monero v8 changes are introduced.

- workaround a simple compare.
- add new device define `OPENCL_DRIVER_MAJOR`

With #1845 a race condition during the telemetry update is solved.
The problem is that the used mutex is blocking all threads from updating the metrics during
the statistics are calculated.

- introduce a mutex per miner thread

fix #1906

If the currency provided by the user is not known by the miner we access an uninitialized value.

Add default values for member of `coinDescription`.
