dmaengine: dmatest: Restore default for channel
commit 6b41030fdc79086db5d673c5ed7169f3ee8c13b9 upstream.
In case of dmatest is built-in and no channel was configured test
doesn't run with:
dmatest: Could not start test, no channels configured
Even though description to "channel" parameter claims that default is
any.
Add default channel back as it used to be rather than reject test with
no channel configuration.
Fixes: d53513d5dc
