Chris Wilson 827db9d8bb drm/i915: Ignore applying the self-relocation BIAS if no relocations
We only need to apply the BIAS for self-relocations into the batchbuffer
iff the execobject has any relocations.

This suppresses some warnings we may get with a full gtt (so the batch
object has wound up at 0 from a previous invocation), but doesn't fix
the underlying problem of how we tried to move a pinned batch vma (how
we have a pinned user vma outside of execbuf, I do not know, though this
being on an aliasing ppgtt means it could be a spurious pinning via the
global gtt). One step at a time...
