This patch completely removes the sync_with_hw() because it was broken and actually there is no point of using it. This function was used to: - Make sure that the submitted packet to the HIQ (which is a kernel queue) was read by the CP. However, it was discovered that the method this function used to do that (checking wptr == rptr) is not consistent with how the actual CP firmware works in all cases. - Make sure that the queue is empty before issuing the next packet. To achieve that, the function blocked amdkfd from continuing until the recently submitted packet was consumed. However, the acquire_packet_buffer() already checks if there is enough room for a new packet so calling sync_with_hw() is redundant.
