[hipDNN] Fix test failures in non-GPU environments by handling hipErrorNoDevice

[averinevg]

Motivation

Tests were failing with error code 100 ("no ROCm-capable device is detected") when run in environments without GPUs. This affected all tests, not just GPU-specific ones, making it impossible to run the test suite in non-GPU environments.

In non-GPU environments:

1. Any HIP API call triggers HIP runtime initialization
2. HIP detects no GPU and sets hipErrorNoDevice (error 100)
3. This error persists and cannot be cleared, even after calling hipGetLastError()
4. The HipErrorHandler test listener checks for HIP errors after each test
5. It detected this persistent error and failed all tests

Technical Details

Modified HipErrorHandler::OnTestEnd() to silently accept hipErrorNoDevice:

• Check if the error is hipErrorNoDevice after calling hipGetLastError()
• If true, return early without failing the test
• This allows tests to run in non-GPU environments
