i965/fs: Don't emit unnecessary SEL instruction from emit_image_atomic().

The SEL instruction with predication mode NONE emitted when the atomic
operation doesn't need to be predicated is a no-op and might rely on
undocumented hardware behaviour.  Noticed by chance while looking at
the assembly output.
