intel/fs/ra: Initialize grf_used with first_non_payload_grf

There's no reason why we need to use the calculated payload_node_count
value which is just first_non_payload_grf aligned up.  The grf_used
value will be aligned up to 16 anyway (which is a much bigger alignment)
before being handed off to hardware.
