ice: remove unused buffer copy code in ice_sq_send_cmd_retry()
The 'buf_cpy'-related code in ice_sq_send_cmd_retry() looks broken.
'buf' is nowhere copied into 'buf_cpy'.
The reason this does not cause problems is that all commands for which
'is_cmd_for_retry' is true go with a NULL buf.
Let's remove 'buf_cpy'. Add a WARN_ON in case the assumption no longer
holds in the future.
