Subject: [PATCH v2] dmaengine: make dmatest less noisy

Commit 95019c8c5 "dmatest: gather test results in the linked list"
started to warning whenever we add results to a test thread.
A warning for something completely normal? This is just cluttering
my terminal. Move to debug prints.

ChangeLog v1->v2:
