[PATCH 2/2] drm/radeon: change call sites to handle return value properly.

Ideally, the failure of set_memory_*() should be passed up the call stack,
and callers should examine the failure and deal with it. Fix those call 
sites in drm/radeon to handle retval properly. 
Since fini functions are always void, print errors for the failures.
