[PATCH] staging: comedi: change some printk calls to pr_err

[Chase Southwood]

There are a handful of calls to printk in ni_stc.h without specified log
levels, as well as one in ni_mio_common.c.  This patch converts these
calls to pr_err() instead, so that they are now explicitly log level
ERR.

I tacked the change to ni_mio_common.c on to this patch since it's the same
exact change and it's just one line, so I think a single patch is justified
here.
