drm/i915: Fix use of uninitialized var in 40a5f0de
i915_gem_put_relocs_to_user returned an uninitialized value which
got returned to userspace. This caused libdrm in my setup to never
get out of a do{}while() loop retrying i915_gem_execbuffer.
result was hanging X, overheating of cpu and 2-3gb of logfile-spam.
This patch adresses the issue by
1. initializing vars in this file where necessary
2. correcting wrongly interpreted return values of copy_[from/to]_user
