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

From: Tianlin Li
Date: Tue Jan 07 2020 - 14:26:09 EST


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.
