Konsta Hölttä 4c62b1aad4 gpu: nvgpu: unit: avoid use-after-free in unmap test

The error path in map_buffer() attempts to unmap a buffer twice to check
that such action does not cause errors. The call site uses a field of a
freed structure in the second call; store that in a local variable to
avoid reading freed memory.
