[PATCH 3/4] Staging: comedi: addi-data: replace printk() with dev_err() in hwdrv_apci1564.c

[Chase Southwood]

There were a small handful of printk() calls in hwdrv_apci1564.c.  It is
generally better to use dev_err() for error messages instead, so I
switched all the printk() calls out, as well as cleaned up the error
strings.
