Fixed the erroneous timeout message in sync-unmap and corrected the condition for returning ETIMEDOUT. In the original codeflow, after waiting for mapped_buffer release, nvgpu_timeout_expired is called to check whether to return ETIMEDOUT. However, if there is a delay between the end of the waiting and the nvgpu_timeout_expired check, ETIMEDOUT is returned regardless if the mapped_buffer is released with the timeout message printed. This is an incorrect behavior. This patch fixes it by letting the refcount of the mapped_buffer be the only source to determine the return value.
