opencl: bugfix increment ref_count in ggml_backend_opencl_init() (#26162)

Incrementing ref_count at the beginning is important later
in the free() method of the ggml_backend_opencl_context at program end.
If we do not increment the ref_count, the result would be -1 here,
and consequently, the profiling data would not be flushed and written.
