ALSA: usx2y: Use standard print API

Use the standard print API with dev_*() instead of the old house-baked
one.  It gives better information and allows dynamically control of
debug prints.

Some superfluous debug prints are dropped, and some ambiguous messages
are slightly rephrased.  The sk.dev pointer is set properly for
allowing to call dev_*() functions, too.
