Subject: Revert "libdrm_radeon: Always wait for BO idle in bo_map."
This reverts commit 0a732983f059c353b267b6bf877e1f0eea4e033f.
Paul Nieminen and Dave Airlie pointed out on IRC that this shouldn't be
necessary. I was seeing visual corruption in X before I made this change, but
I can't reproduce that anymore so it was probably an unrelated issue.
