[Mesa-dev] [PATCH] i965/drm: Delete NULL check in brw_bo_unmap().

[Kenneth Graunke]

I accidentally moved the bo->bufmgr dereference above the NULL check
when cleaning up this code.

While passing NULL to free() is a common pattern...passing NULL to
unmap seems pretty bad.  You really ought to know whether you have
a buffer or not.  We don't want to paper over bugs like that.  So,
just drop the NULL check altogether.
