accel/amdxdna: Fix cu_idx being cleared by memset() during command setup

Browse source

For one command type, cu_idx is assigned before calling memset() on the
command structure. This results in cu_idx being overwritten, causing the
firmware to receive an incomplete or invalid command and leading to
unexpected command failures.

Fix this by moving the memset() call before initializing cu_idx so that
all fields are populated in the correct order.
