This commit adds a while(true) loop to the no_device_code function in common.cuh. This is done to suppress the warning:

/ggml/src/ggml-cuda/template-instances/../common.cuh:346:1: warning:
function declared 'noreturn' should not return [-Winvalid-noreturn]
  346 | }
      | ^

The motivation for this is to reduce the number of warnings when compilng with GGML_HIPBLAS=ON.

Try modifying the __trap macro like this instead:

#define __trap() do { abort(); __builtin_unreachable(); } while(0)

Update __trap macro instead of using a while loop to suppress the
warning.
