r300: Workaround hardware readcache problem

This workaround is similar to the one found in r200_span.c.
It seems like some part of the read hardware doesn't realize that
VRAM has changed. By reading from an arbitrary position, this is fixed.

The piglit test bugs/r300-readcache is a regression test for this bug.
