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.

On my system the default log level is 4 which corresponds to
KERN_WARNING. So switching to pr_err() would change the log level
of these messages. Using pr_warn() might be a better choice.

I wouldn't worry about the log level in this case as those printks would
only be reached due to driver bugs.
