During the processing of a user SDMA request, if there was an error before the request counter was increased, the state of the packet queue could be updated incorrectly, causing the counter to underflow. As the result, the process could get stuck later since the counter could never get back to 0. This patch adds a condition to guard the packet queue update so that the counter is only decreased if it has been increased before the error happens. Reviewed-by:
