i965/fs: Add missing analysis invalidation in fixup_3src_null_dest().
Bug found by the liveness analysis validation pass that will be
introduced in a later commit. fixup_3src_null_dest() was allocating
registers which makes the cached liveness analysis calculation
incomplete, so it must be invalidated.
