* Test Type: Feature, Error guessing, Boundary values

* Targets: nvgpu_queue_alloc, nvgpu_queue_free

* check that the API returns "-EINVAL" error.
* - Pass "INT64_MAX" size queue length as argument to nvgpu_queue_alloc() API
* and check that the API returns "-EINVAL" error.
* - Inject fault so that immediate call to nvgpu_kzalloc() API would fail.
* - Check that when the nvgpu_queue_alloc() API is called with valid arguments,
* it would fail by returning "-ENOMEM" error.
* - Remove the injected fault in nvgpu_kzalloc() API.
* - Pass below valid arguments to nvgpu_queue_alloc() API and check that the
* API returns success.
* - Valid pointer to "struct nvgpu_queue"
* - Queue size which is not power of 2
* - Free the allocated queue by caling nvgpu_queue_free() API.
