drm/radeon: fix non revealent error message
commit 8d1c702aa0b2c4b22b0742b72a1149d91690674b upstream.
We want to print link status query failed only if it's
an unexepected fail. If we query to see if we need
link training it might be because there is nothing
connected and thus link status query have the right
to fail in that case.
To avoid printing failure when it's expected, move the
failure message to proper place.
