Well, if there's adequate error reporting in init_dai_link() it's a bit
different - we can just remove the print entirely regardless of what the
return code is.  The point is to ensure that we don't just silently
fail.  Unfortunately there's no prints in the probe deferral case there
so they need adding, that'll actually improve things though since we can
make it print the name of the thing it's mising which will be useful to
people trying to figure out what's going on (we used to do that but it
got lost in reshufflings).
