drm/i915: Clarify relocation errnos
While trying to find a random -EINVAL from a failing test, I noticed we had a few hard to follow return values. The first two hunks in this patch replace completely useless initialization of ret. The last several hunks help to distinguish between altering 'return ret' and 'return <ERROR>' Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
