Lizhi Hou 3464e75175 accel/amdxdna: Validate command buffer payload count 
[ Upstream commit 901ec34709 ]

The count field in the command header is used to determine the valid
payload size. Verify that the valid payload does not exceed the remaining
buffer space.

Fixes: aac243092b ("accel/amdxdna: Add command execution")
