The debugfs files always in this driver all use an extra round-trip
through an snprintf() before getting put into a mlx5dr_dbg_dump_buff()
rather than the normal seq_printf().
Zhu Yanjun noticed that the buffers are not initialized before being
filled or reused and requested them to always be zeroed as a
preparation for having more reused between the buffers.
I think that you are the first to find this.
