drm/radeon: Fix sparc regression in r300_scratch() 

Commit b4fe945405 ("drm/radeon: Fix
memory allocation failures in the preKMS command stream checking.")
added a regression in that it completely tossed the get_unaligned()
done by r300_scratch() which we added in commit
958a6f8ccb ("drm: radeon: Fix unaligned
access in r300_scratch().").

Put it back.
