i965/fs: Move perf_debug about register spilling to a more obvious spot.
The if (!allocated_without_spills) block is an obvious spot for this
performance warning message.
In the Vec4 backend, scratch is also used for indirect access of
temporary arrays. The FS backend doesn't implement that yet, but
if it did, this message would be inaccurate, since scratch access
wouldn't necessarily mean spilling. Moving it preemptively fixes that.
