Subject: [PATCH 1/7] accel/amdxdna: Fix incorrect command state for timed out job

When a command times out, mark it as ERT_CMD_STATE_TIMEOUT. Any other
commands that are canceled due to this timeout should be marked as
ERT_CMD_STATE_ABORT.

Fixes: aac243092b70 ("accel/amdxdna: Add command execution")
