Revert "intel: don't apply the relocation optimization if a target"
This reverts commit e2cb905bc6e23eaafaeeb2abdc9480e70959ee3f.
It was a reversion of an optimization hidden as otherwise.
pre_target_buf_handle was always NULL, so the optimization was never enabled,
rather than fixing the important optimization (resulting in 25-50% performance
loss).
