drm/radeon/kms: Fix r600 blit cleanup path
r600 blit cleanup path need to check if a bo was allocated before trying to free or unpin it. This patch add this check and avoid oops when the initialization on r6xx or r7xx hw fails. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
