i965/fs: Fix copy propagation with smearing.

We were correctly relaying the smear from MOV's src, but if the MOV
didn't do a smear, we don't want to smash the smear value from the
instruction being propagated into.  Prevents a regression in the
upcoming UBO change.

Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
NOTE: This is a candidate for the 9.1 branch.
